Description stefan79 2012-11-02 14:20:42 UTC

[ BUILD # : 201211020001 ]
[ JDK VERSION : 1.7.7 ]

Today I pressed at the "Build Project" - button.
After about 15 minutes, this ends in an OutOfMemoryError and the IDE was
unresponsable.
I tried to make Thread - Dump, but jvisualvm doesn´t shows the IDE.


Compiler-Log is showing that the copy-Action has finished.

Dump was uploaded to hudson.
-> http://deadlock.netbeans.org/hudson/job/upload/86/

Comment 4 Tomas Hurka 2012-11-05 10:37:23 UTC

It looks like checking for LowMemory does not work well.

Comment 5 Tomas Hurka 2012-11-05 10:38:17 UTC

Heap dump available on request.

Comment 6 Tomas Zezula 2012-11-05 15:37:27 UTC

Added logging jet-main 406bbad27b82.
Seems a problem with MemoryMXBean.
Please can you run the IDE with -J-Dorg.netbeans.modules.parsing.lucene.support.LowMemoryWatcher.level=FINEST option and retry to reproduce the problem?
You will need a build containing the changeset 406bbad27b82.
Thanks!

Comment 8 Tomas Zezula 2012-11-06 18:57:32 UTC

Please attach the log with the -J-Dorg.netbeans.modules.parsing.lucene.support.LowMemoryWatcher.level=FINEST and reopen then.

Log-File.

OutOfMemoryError occured again at current build (201211120001).
LowMemoryWatcher was activated.

I´ll upload the Dump to hudson.

Comment 10 stefan79 2012-11-12 15:22:39 UTC

Dump is available at hudson:
http://deadlock.netbeans.org/hudson/job/upload/99/

Comment 11 Tomas Zezula 2012-11-12 18:34:52 UTC

Seems very strange as right before OOM there were nearly 300MB of free space:
 Max memory: 1.908.932.608, Used memory: 1.617.979.552,

Log-File after restarting (OOME occured again)

Yesterday this was the same story:
-) I refreshed some source files (update CVS)
-) NB started Background-Scanning -> OOME occured
-) I restarted NB -> OOME occured again
-) I restarted NB -> OOME occured again
-) I cleared the Cache-Directory and startet NetBeans again -> It works

Comment 13 Jan Lahoda 2012-11-14 13:06:05 UTC

Tomas, you are looking into this, right?

Comment 14 Tomas Zezula 2012-11-20 22:11:28 UTC

Restored the behaviour of LowMemoryWatch not to cross the CMS stop the world limit.
