@vstejskal: I'm not sure, but it looks like problem during scanning. Maybe we are not able to utilize memory usage more
and it just happens.

@reporter: Please increase maximal available memory -Xmx to higher. It can help.
Comment 4 Vitezslav Stejskal 2009-05-18 12:23:01 UTC
Do you have a heapdump? If not could you please change your IDE so that it generates one when OOME happens next time and
then upload the heap dump to editor.netbeans.org? http://wiki.netbeans.org/FaqMemoryDump
Thanks
Comment 5 rkamradt 2009-05-22 17:05:08 UTC
I have a heapdump file, how do I upload it to editor.netbeans.org?
Comment 6 rkamradt 2009-05-22 20:42:36 UTC
I upped Xmx to 1024M and that solve the problem with one project, however during project scanning the memory goes as
high as 800M.  That is with a single set of projects open, and I used to work with up to 4 sets of projects at once in 6.5.
Comment 7 rkamradt 2009-05-23 00:11:23 UTC
Eventually even at Xmx1024 it ran out of memory.
Comment 8 Vitezslav Stejskal 2009-05-25 11:51:00 UTC
"how do I upload it to editor.netbeans.org?" - Go to http://editor.netbeans.org, in the right hand side menu click
'Files' and then 'Add new file'. This will let you upload the heapdump. Please give it some meaningful name. Thanks
Comment 9 rkamradt 2009-05-26 15:11:03 UTC
The heapdump is 464M, bigger than the file limit at editor.netbeans.org.  Is there a way to reduce the size?
Comment 10 Vitezslav Stejskal 2009-05-27 09:23:48 UTC
Can you somehow split it to two/more parts and upload them separately? I think for example 7zip allows creating archives
of specific size and it's available on both Win and Linux (among others). Thanks
Comment 11 rkamradt 2009-05-27 15:18:39 UTC
I assumed that it wouldn't compress well, as it turns out zipping it reduced it to < 100M  It's uploaded
Comment 12 Vitezslav Stejskal 2009-05-27 17:17:10 UTC
Thanks!
Comment 13 Dusan Balek 2009-05-28 12:56:08 UTC
There are 282 instances of the javac compiler (as can be seen from the uploaded heapdump). Looks like an incarnation
of #162133, which should be fixed in the current dev build.
