I haven't had that serious problems about downloading with JDownloader at all, but it uses too much of RAM, generally about 250 MB (actually from 80 MB up to 530 MB). Is it a normal occasion?

I've tried to installing the latest known versions of Java and JDownloader to fix this, but unfortunately it didn't help and javaw.exe is still killing the PC.

I have a theory: the RAM value that JDownloader uses is directly proportional with the size of the file being downloaded at the moment. Because it's generally about 250 MB while downloading standard 200 MB parts from Rapidshare; but when it comes to bigger files (just like the single file of 4.5 GB which I am downloading right now), JDownloader starts to use more RAM. Now JDownloader has downloaded 1.7 GB/4.5GB and the task manager result is just like the given below (528 MB!). I'm afraid it will continuie to incrase, it's been about 532 MB until now, while I was writing these lines:

boardsearch->there are already threads about this issue, that some users have..

we are still trying to find the cause for this, but not that easy when no dev has this issue himself.

we are working on it

All the devs obviously have way too powerful machines They should be restricted to Pentium-III machines with max 512 MB RAM. Then the app would be lightweight and lightning fast :D

jd runs fine on my eeepc 701
the named issue is known and we are still trying to find it.

@Araldo
Right, i have a quad core and so on xD
I wouldn't notice it if i had the ram bug:w00t:

RAM usage is not the problem, if it uses 10, 100 or 1000 MB doesn't matter to me. Only the high CPU usage that slows down the whole machine is annoying. As others already wrote, happens only when download list is visible. Minimizing or switching to linkgrabber, settings or log immediately lowers CPU usage to acceptable values comparable to older versions.

My main JD runs on a Windows Server 2003 Enterprise virtual machine hosted by VMware Server 2.0 on a linux machine with P4 singlecore 1.7 GHz and 1.5 GB RAM (VM gets 1024 MB currently). No Antivirus, no third party firewall. Here the high CPU is really a pain, was much much better in the later 0.7xx nightlies.

I've got the same problem... and more - JD is literally killing my machine from time to time... HDD activity raises to hell (it looks like PC's trying to decompress something over and over again) and the only way to do anything on my PC again is to kill JD process in task manager...

P.S.

and of course when this problem occurs, JD stops downloading :/

We need more Information! We are still trying to find the cause for this, but till now none of us developers could reproduce this mem/cpu usage.

What Java Version? What OS? where is jd installed? what antivirus/firewall?

Tried a clean fresh installation too?

OS:Windows XP (SP3, all updates installed)
Java: 1.6.0_07
Installation folder: c:/JDownloader 0.7
Firewall/antivirus: windows firewall, no antivirus

yes i've tried clean install, didn't help a bit. This doesn't happen all the time but often enough... i'm not mad or anything, i know that debugging and fixing the code is a pain in the ass i'm just reportin a bug

[Jiaz]

so it also happens with a complete fresh installation (no config copy from old one)?

yep, iv'e deleted all of the JD and installed a brand new copy...

[Araldo]

OS: Windows Server 2003 Enterprise SP2 32bit
CPU: Pentium4 1.7 GHz
Memory: 1024 MB
Java: either 6u16 or 6u18 b02
Style: Synthetica Simple 2D, Window decoration off
Antivirus: none
Firewall: Windows Firewall
Other software running the same time as JD: none
Installed at: c:\Programme\JDownloader (Win2003 doesn't have program folder protection)
Fresh install: yes, exported download list to DLC, moved whole JD-folder away, extracted 0.8 stable to new empty folder, imported the DLC and configured all settings from scratch. Didn't copy database or settings from old install.

The high cpu usage wasn't there in the nighlies until IIRC 2-3 days before official release of 0.8, then it appeared in nightlies and also was there in 0.8 stable.

Did you try to disable the jD-Unrar and other add-ons?

yep, all plugins disabled, except for the "hide to tray" plugin.

What I would try now is to install an older JRE. I see that your JREs are rather recent.

Please disable the following columns in downloadview

* Status


Does the problem still exist with disabled Host and Status column?

Hi,

I hv been using jD about a year ++. version 0.8.324 was start using yesterday. the result:

2x application hang
High ram usage --> slow jD response
High CPU usage

If ram usage is too high, jD response will become slow, and if it was minimized, tada!!! jD will hang...and all download stop. We hv to force end task and restart it.

I disable everything...unrar, hjsplit, sceduler, and such. the only active addon is minimize to tray.

All of these i had nvr exp in jD 0.6.193, the best + smooth jD so far. I skip 0.7 due to it is extremely unstable.

p/s: jD just hang whle i'm typing these guess..i've to revert to 0.6.193




original size: lh6.ggpht.com/_SBcoSrt1i0Y/SrxqxfKISJI/AAAAAAAAANg/BdPPGlh7UAU/d/memory.png

as you can see, javaw.exe, that is jD, uses about 620Mb ++ RAM. at application start, jD only utilize 160-180Mb ±100Mb RAM. The amount continously increase overtime. Whenever it reaches 620++Mb, jD will hang and crash.




My PC spec:
MS Windows 7 Ultimate x86 build 7264
INTEL Xeon Quad X3320
BIOSTAR TP43 HP
COLORFUL GeForce 8600GT OC 256DDR3
4x HP/Micron 1GB DDR2 800Mhz
SILVERSTONE ST56F
1x SEAGATE 80Gb SATAII
1x SAMSUNG 500Gb SATAII

yep, nothing's changed in that matter...problem still exists.

We finally found the cause of the mem/ram issue and will test it ! I think next week we will release an update with the bugfix

hope that will solve the problem

update: it appears that for version 0.8.324, if jD is minimzed to tray, it wont utilize much ram. if it was minimized at 150Mb ram, the value will stay around 150Mb for hours. it it was at 130Mb, it is ±130Mb for hours.

My congratulations! I'm curious what it was and why only few people had it.
