All the FS calls are waiting for monitor on 0x7d6f0990 which is owned by thread "Pending refresh".

"Pending refresh" daemon prio=10 tid=0x63c72000 nid=0x1469 runnable [0x64ce0000]
   java.lang.Thread.State: RUNNABLE
	at java.lang.Thread.holdsLock(Native Method)
	at org.netbeans.modules.masterfs.filebasedfs.naming.NamingFactory.cleanQueue(NamingFactory.java:402)
	at org.netbeans.modules.masterfs.filebasedfs.naming.NamingFactory.registerInstanceOfFileNaming(NamingFactory.java:220)
	at org.netbeans.modules.masterfs.filebasedfs.naming.NamingFactory.fromFile(NamingFactory.java:111)
	- locked <0x7d6f0990> (a java.lang.Class for org.netbeans.modules.masterfs.filebasedfs.naming.NamingFactory)

It's not clear how long it takes.

To reporter: Please if you can reproduce it can you either create IDE self profile (nps file) or 3 successive thread dumps with 5 seconds delay. Thanks a lot.

I think this may be the real problem:

I can see (self?) profiling was running. Can I get the profiling snapshot please?
Comment 5 gholmer 2012-05-18 12:36:01 UTC 
Where will I find this? NB: I typically install the latest dev build every morning, deleting the contents of the install and user dirs and re-importing the userdir from 7.1.x.

Comment 7 gholmer 2012-05-18 15:40:09 UTC 
Ah! then I am afraid if there was one, it is gone forever (see comment 5). I never got as far as seeing it in the IDE.
Comment 8 Tomas Zezula 2012-05-21 09:23:56 UTC 
Thanks for help.
