Hello,
I'm receiving frequently java.lang.OutOfMemoryError: Java heap space errors.
I did increase the settings in Eclipse.ini to the following values:
-Xms356m
-Xmx640m
-Xmn128m
-XX:+UseParallelGC
-XX:MaxPermSize=256
If I monitor Eclipse in the Windows task manager I see that Eclipse is
around 230 MB before crashing; to my knowledge my settings should be
sufficient.
The system asked me to check .log for additional information but I cannot
find any .log files other then the install.log and error_recovery.log, both
do not contain additional information.
Any advice?
Best regards, Lars

Lars,
If your settings were taking effect, you'd get up to 640. Look in the
<workspace>/.metadata/.log for track traces. Is it regular memory or
permgen that's running out? My eclipse.ini looks like this so I'm not
sure your max perm size is quite right.
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vmargs
-Xms40m
-Xmx256m
You might have to run with -clean for eclipse.ini changes to take
effect. And note that in 3.3.1 the launcher argument was being ignored
and that was fixed in 3.3.1.1.

Hi Walter,
with the increased parameters from Ed I did not yet receive a dump.
So currently me eclipse.ini looks like the following:
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
512m
-vmargs
-Xms40m
-Xmx512m
-XX:+HeapDumpOnOutOfMemoryError
If I receive this error again I will make the HeapDump available if that is
useful.
Best regards, Lars

Hi Eric,
usally Eclipse becomes unusable after this error. In some cases I can close
it in some I have to kill it via the task list.
If it happens again (I changed the settings) I try to report more.
Best regards, Lars
