Created attachment 150580 [details] messages log See also https://netbeans.org/bugzilla/show_bug.cgi?id=246329 I have exactly the same memory issues as described in the above-mentioned bug report. The difference being my OS and my JDK (Windows 7-32 and JDK 7). After extended use the memory in task manager reports anywhere from 620MB to 710MB. The NB Performance toolbar incorrectly reports the memory usage as 390+MB and never goes over 400MB, which is completely false. I will attach the messages.log When in this state the IDE will not refresh the Project and Navigator viewports and the code viewport is very slow to react to any user input.

This can cause the problems you see in Projects and Navigation. Reassigning to asp for further investigation.

I have since updated the IDE to 802 and the issue still happens - the symptoms are as described above. The performance toolbar show 390+MB while NetBeans.exe in task manager shows 600-700MB and the java.exe process that is linked to NetBeans.exe uses about 180MB. Performance is horrendous - refresh rates are ridiculous - just switching from one file to another can take over 30 seconds. The only way to temporarily "fix" the issue is to restart the IDE completely.

Some more observations: This issue seems to occur when having multiple files open in the editor (of multiple different types (in my case: jsp, java, css, js)). The problem progressively gets worse the more I switch between and edit/save different files.
The ISE is just a warning (though deserves some investigation). Please provide a heapdump and reopen so we can investigate the leak. http://wiki.netbeans.org/FaqMemoryDump
