However, Windows and the drivers are running in 64 bit mode, so you need the 64 bit patch.

Thank you! Last question I swear, you have been so very helpful - so I have been using jDownloader for about 12 hours here nonstop, have done all of the things that you suggested including ERUNT, QoS stop, running the cmd, all well and good, speeds seem good. My Task Manager shows that physical memory is at 43-45%, has been around that since I checked this morning. Since this morning, javaw.exe has gone from 440,000 K to ~460,000 K Memory. I have 8 Gig ram, 64 bit win 7. I'm basically trying to determine if I need to run that hotfix or not -- I don't know how to tell if I have the memory leak, and what I've read on the web suggests that if you don't need this kind of hotfix, you shouldn't use it. Does this memory use seem in line with nonstop full bw jdownloading for > 12 hrs? Or does this seem high? I have been reading various forum threads trying to determine if I'm a candidate for the hotfix or not, this memory usage seems high to me, but then it seems like others have horror stories about their PCs locking up, and 90% phys memory usage. So I'm hoping as the authority on this, you have some input.

Thanks again!

JDownloader normally starts with a limit of around 550MB (512 in the heap, plus the runtime). These numbers are reasonable.

Some of the memory leak has to do with your antivirus or firewall. If you are doing this well, please let us know what you are using for antivirus and firewall.

With 8GB of physical memory, Java programs can use up to 3GB of Virtual Memory. You are a long way from system problems.

I think the reason that your overall physical memory use is so high is that the OS has allocated a large amount of memory for the disk cache (you have it, so Windows uses it). As long as the "Total Private bytes" for all programs is less than your 8GB, you are in very good shape.

These are general instructions for the worst case of all: JDownload does not work.

Before each change, backup JD (Ctrl+B).
After each change, restart your computer and test JDownloader.

1) Please make sure you have Java 32 bit JRE 6 update 21 installed
(open a command line and type "java -version" without the quotes).
If you have a different version, uninstall Java and install this version. Please see Java Problems - JD Hangs, Freezes, Doesn't Start to install this version of Java.

2) In Windows if "java -version" gives you an error message, make sure that the java directory is immediately after the Windows entries in your system path. In Windows, open the properties for My Computer, open the Advanced tab, and press the Environment Variables button. Click on the "path" variable in the System section (the second box) and click on Edit. Move the cursor after the three Windows paths and then insert ";%PROGRAMFILES%\java\jre6\bin;".

3) In Windows Vista or later, make sure jdownloader has full privileges to read, write, and execute in its directory. As an administrator, reinstall JDownloader into a directory like c:\jdownloader.

4) In Windows Vista or later, make sure to install the Required Patch listed in the stickies of General Discussion.

5) Please make sure that your antivirus and firewall give complete rights to JDownloader, Java, and Javaw. Make sure that your antivirus does not scan your network data (no web or link scanning, checking, or shield). If any of those features are installed in your antivirus, follow the instructions in Choosing and Installing Security Software.

6) Start JDownloader using the instructions in General Discussion -> Self Help Index -> Posting an Emergency Log. This provides more information in the log and saves it to disk (so the freezes do not affect the log). Make sure to create an archive containing the txt files this creates and any hs_err*.log files in the JDownloader directory. Attach the archive to a message containing the information requested in the rules (usually General Bugreport).

7) Change the Emergency Log batch file so that the Java line begins with
"java -Dsun.java2d.ddscale=true " (no quotes)
Does this help?

8) Update to the Nightly Test release and see if that helps. Use the file in (4) to start JDownloader. If that works, try starting JDownloader the normal way and see if that works.

[drbits]

An emergency Log contains more information from java than an ordinary Log.

1) Start JDownloader. If you cannot do this, skip to step 4.
2) Set Settings -> Basics -> Log level=All
3) Exit JDownloader.
4) Open a command window (Start -> Run -> CMD for Windows) or terminal window for Linux and OS-X.
5) Change directories to the JDownloader directory usually one of the following for Windows

cd c:\programs\jdownloader
cd c:\jdownloader
cd c:\program files\jdownloader
cd c:\program files (X86)\jdownloader
cd d:\program files\jdownloader

6) Start JDownloader by typing this into the command window (OS-X users, leave out the -Xmx512m parameter):

java -verbose -Xmx512m -jar jdownloader.jar -debug -brdebug 1>javalog.txt 2>jderr.txt

If JDownloader still does not start use

java -verbose -Dsun.java2d.ddscale=true -Xmx512m -jar jdownloader.jar -debug -brdebug 1>jdlog.txt 2>jderr.txt

7) Run your test (provoke the error).
8) After the error has occurred, exit JDownloader.
9) The jdlog.txt and jderr.txt are two different kinds of Logs. jderr.txt is like the normal Log. jdlog.txt is from Java.
10) Make a rar archive of the two files.
11) Open a message in the appropriate forum and explain your problem or anything extra you have learned. List any links and/or passwords you used. List your Maximum Connections per file. Make sure to include your OS and version, Firewall, Antivirus, and any other programs running at the same time as JDownloader (in any request for help).
12) Click on "Go Advanced". Click on "Manage Attachments"
13) Click on Browse, find and select your rar file.
14) Click on Upload. When Upload finishes, click on "Close this Window"
15) Your message should show that the file is attached.
16) Click Submit Message.
17) If you changed your Log Level, start JDownloader, Set Settings -> Basics -> Log level=None, Exit JDownloader.

The search system at JDownloader.org is quite good and in the advanced search you can reduce the number of results tremendously by restricting the search to Titles only.

However, the vBulletin software does not always return the entries you want (especially in the Reconnection Forum). It is restricted to words of 4 letters or more that are not in the list of common or unfriendly words (the stop list). This list is applied to parts of words, not just whole words. This is not a JD problem, it is a result of using vBulletin, otherwise great forum software.

As an alternative, you can use Google.

All public portions of this web site are frequently indexed by Google. Any entries that have existed for a while can be found by using
Google <your search terms> site:jdownloader.org
or
Google <your search terms> site:board.jdownloader.org

In the Reconnect forum, where short "words" are used in the model or version of a router. Important words like IP are not indexed by the board software. In this case, employ "site:board.jdownloader.org/forumdisplay.php?f=2" to search directly in the Reconnect forum.

Especially when you have a problem with the user interface (GUI), screenshots can provide valuable information for solving the problem.

First, resize the window you are interested in by dragging the corners or edges. You usually don't have to capture a huge or full-screen window.

If you don't already have a screen capture program, please install the Freeware version of FastStone Capture (attached to this message).

If you don't already have a favorite Photo Host (not a file host), then we suggest ImageShack.us (because you don't need an account) or FileAve.com (because of their high ratings and generous free accounts). Copy the underlined names to your Browser address bar. Remember, only download photos from these hosts, they do not check for viruses.

The easiest way to use a Capture program

a) Once the program is running. Click on the window to be captured and press Alt+Print-screen (usually above the Insert key on full size keyboards).

b) You will be asked where to save the image. Choose File. The desktop is usually a good place to store a file for a few minutes. You also have to choose a format:

PNG files are a good choice of format for showing small details.
JPG files are smaller and a little blurry, but usable, and
GIF files are usually the smallest and clearer than JPG files, but the colors are not preserved.

c) If your image needs editing, any image editor from the past few years can read and write all three of these formats. If you know in advance that the image will need editing, save it from the screen as a PNG and then save it in your preferred format from the editor. It is not a good idea to use the on-line editors.

Uploading

The Image storage sites present you with a browse box. If all of the images to upload are in the same folder (for example the Desktop), then click on the first file and Ctrl+Click on each of the rest. Click on the Select button (may be labeled Open or Save) and your images should be uploaded (sometimes you also have to click on an Upload button).

Posting

Usually hovering the mouse pointer over an image or clicking on an image will give you a choice of different kinds of links. If it is a large image intended for support staff, choose the "Direct Link". If it is a smaller image, intended for everybody, choose the BBcode (or bulletin board) link that automatically adds the tags so that the image appears.

If you are posting more than two or three images, select all of the images and create a "Spoiler" with the Blue letters icon (you might have to "Go Advanced").

Some sites offer thumbnails or HTML code, avoid using those features.

To Backup your Links-list and settings
JDownloader saves the data to a temporary file on disk every 10 minutes.
When the program exits, the data is converted to a script and the temporary file is deleted.

The data is saved to disk in <<database.zip>> in the jdownloader\backup directory.
To make a backup, use File -> Save -> Save Backup (Ctrl+B). Make a backup every day.


To restore your Links-list and settings:

1. exit the JDownloader program (consider restarting your computer),
2. browse to your jdownloader\backup directory,
3. choose a ZIP file (use the modified date),
4. open the ZIP file (double click),
5. drag the files from inside the ZIP file to the jdownloader\config directory (overwrite the existing files), and
6. Start the JDownloader program.

Java Update Breaks JDownloader

If JDownloader breaks when you update Java, please try
Java Problems - JD Hangs, Freezes, Doesn't Start

Your security software can cause this.

If you are using an antivirus or firewall that requires you to create exceptions for jdownloader, java, or javaw, updating JD or java should cause the security software to start blocking again.

When a program has changed, well designed security software will ask whether this is an update of the same software. If it is an update, the old exception should be applied to the new version as well.

In any case, the security software must tell you when it is about to block a program. If you cannot set this up, then the security software should be uninstalled.

Read Choosing and installing security software for more information.

[drbits]

1) Incomplete downloads or CRC errors
a) If this happens only on larger files, it is probably a problem with your Antivirus. Please see Choosing and Installing Security Software.
b) If you get a lot of incomplete downloads, you probably have too many connections. Please see Optimizing Your Number of Connections.

2) No downloads at all.
a) Is it plugged in?
b) Is your firewall blocking JDownloader.exe, Java.exe, or Javaw.exe? Please see Choosing and Installing Security Software.
c) Check for hs_err*.log files in your JDownloader directory to see if there is a problem with Java and your hardware. Older video cards are a problem with some Java updates.

3) DLC or CNL do not work
a) Your firewall is keeping Java or Javaw from listening on port 9666

4) Security errors or No Permission to Write to Hard Disk
a) You are using Windows 6.x (Vista or "7") and JDownloader is installed in the Program Files or Program Files (x86) directory.
b) Either part of the JDownloader directory or your download directory are protected or read only.
c) You are running multiple copies of JDownloader from the same directory or trying to write to the same directory.

5) You cannot download from a host
a) The government, your ISP, or the host server is blocking your connection. Try other hosts to figure out if this is happening. Also try your browser.
b) The host has changed their software and JDownloader's plugin needs to change (Plugin Error (out of date)). See Hoster Plugins rules.

5) A feature that worked before is not working
a) You are using Nightly and a feature is missing (being reimplemented).

6) JDownloader has a bug. In order to fix it, the developers need information. See General Bugreport rules for a sample list.

7) Bill Gates has broken your computer or allowed somebody else to install malware on your computer. See the Self Help Index. Or somebody lied to you and told you that there is no need for an antivirus or firewall on OS-X and Linux.

8) You want to change your IP address, but either have a difficult router or ISP or you haven't read the related messages. Read Getting Started with Reconnection in the Reconnect forum.

9) You have a great idea! Or you want support for a new host.
a) Please search before posting it, because there is over a 75% chance that it is already in the BugTracker or already rejected.
b) Post your idea in a new thread in Suggestions and Wishes. See the Suggestions and Wishes rules for the information we need.

The internal backup (Ctrl+B) backs up the entire JD database as a text representation of the Java Objects in the database. It includes the links list (including full status) and all of the settings (see jdownloader -config). To restore of of these backups, one extracts the two files (database and database configuration) from the ZIP file and overwrites the file already in the jdownloader\config directory.

The container backup (JDC/DLC) backs up the web addresses (URIs) in the Links List inside an encrypted container. The Backup command backs up the whole Links List. There is also a context menu command for creating a container from the selected packages or links.

Containers only backup the web addresses of the files, not the download status or the settings. Furthermore, they are intended to hide the web addresses, so if a links list is restored from a container, the web addresses are not available to users. This confuses most users.

JDCs are only for local backup, not web use. They are encrypted, but the user supplies the password. A ZIP file of the database with a user supplied password is just as secure and provides a full backup. (Personal note from drbits: Do not uses this for backup).

That the Ctrl+B backups are always in the JDownloader directory is a problem. If the partition containing the JD directory dies, the backups are also unavailable. The entire JDownloader directory (or at least the last few backups) should be backed up to external an medium on a regular basis. Then any old backup ZIP files can be removed from the disk.

DLC's are highly secure containers. Encryption/decryption of one of the passwords occurs on a JDownloader.net server using a high quality key that is private to those servers. So they have a password only known to JDownloader management and a random password supplied by the local computer. The security is comparable to that provided by banks for ATM machines. Using Click'N'Load with an encrypted web address for a DLC plus the security of the DLC and (when possible) HTTPS communication with file server provides confidentiality of the location of files so that they cannot be hacked or censored.

The dialogue for backing up to a JDC should add an extension if none of the known container extensions is provided. For now, we need a message to provide the extension.

Eventually, there should be a Restore from Backup command that creates a backup of the current database,
presents a file selection window and then does the ZIP extraction, overwrites the config directory, and restarts JD (without saving the database). This requires a setting in User Interface -> Advanced that provides the directory for the Backup ZIP files.
