dev build Try leaving Netbeans running for over 30 mins doing nothing and soon enough it'll leak so much memory that GC will be running 100% of the time. Please fix this before you ship 4.0 final. Sorry I don't have more accurate repro steps. On my end, I did some CVS commits, CVS refresh then left Netbeans minimized in the background. It kept on doing cvs refresh in the background (I think this is a recent new bug) but aside from that nothing else was going on. 30 mins later I come back and memory is capped at 200MB and the GC is churning away.
sorry, dev build 200408231800
reassigne to perf team for evaluation
I frequently leave Netbeans running doing nothing and did not encounter any leak. So, as you say, this is related to the CVS refresh running on the background in the IDE. Reassigning to VCS folks.
This is most likely a duplicate of issue #47958. It's fixed in recent builds, there should be no infinite refresh any more. *** This issue has been marked as a duplicate of 47958 ***
Verified.
