NOD32 WebScanner/HTTP SCanner is known to cause all kind of issues
-memory leaks
-bsod
-java crashes

every user reporting such probelms and having nod32 could fix it by disabling the http/webscanner

so pls try this first

Besides: pls use a proper java tool for monitoring memory usage, because all windows tools (taskmanager and process explorer) cant show it right..you have to differ between java-jd-heap (your tool just mix them)
java memory is heavily depending on machine, os, java version and installed software
heap memory is heavily depening on machine, os, java version, installed software and such things

i check jd very often about memory leak issues and my last test was 72h with no mem leak found
