Forwarding original message from Tad Frysinger, with my comments.

I have closed down NB6 IDE - 5 minutes later my system has one java
process consuming 98% memory.  The only programs running now are
Thunderbird, Windows Media Player, FireFox, and Task Manager.

Attaching task manager screen shot.  This is a pretty serious IDE
performance hit that should not see FCS.


Best,
David


Ditto for me Tad.  New install RC2, WinXP, 1.5GRam - one tiny VWP
project.  I get Windows virtual memory dangerously low error messages.  
My system is unusable, I take a break for an hour - system now usable.  
Memory use at 264MB, I couldn't bring focus to the IDE during the memory
outage to record memory used, everything was frozen.  David

Did you get a thread dump?  This is crucial if the NB team is to get a handle on what may have gone awry.

I tend to run NB through the nb.exe on Windows so that I can ctrl-break and get the thread dump if necessary.

Daniel, Thank you for the clarification on running nb.exe - I haven't tried it before because I didn't really understand it; I will do so from now on and will catch my elusive thread dump.  Do you mind if I cross-post this to nbusers, where there are at least two users writing about the same problem?  Best, David

Quitting out after this and going back in - memory is now steady at 225MB.

Seems like there is 300MB that could be better managed somehow...?

I would add that in case of such a problem, you can use jps/jstack to see
what is actually the java process doing (calling jstack several times to
have even better idea) even without using nb.exe, and maybe also jmap -histo/-dump
to see why is it using given memory.

There is one final option which is the Visual VM
https://visualvm.dev.java.net/, although this only works when NetBeans is run
under JDK6.

David, feel free to share this information.
