Build: NetBeans IDE Dev (Build 201205040400) VM: Java HotSpot(TM) 64-Bit Server VM, 20.6-b01-415, Java(TM) SE Runtime Environment, 1.6.0_31-b04-415-11M3635 OS: Mac OS X User Comments: mrpc: Opened a project, scanned for git changes, ignored a couple of folders and netbeans slowed down way too much for a while. I don't know what action trigered it so I can try to reproduce, but I will try to do everything again later.

If possible provide a thread dump when the problem happens again: http://wiki.netbeans.org/GenerateThreadDump A pointer to a heap dump would help as well: http://wiki.netbeans.org/FaqMemoryDump Thanks.
