Continuing Out Of Memory (PermGen) errors

[wsonner]

I'm continuing to get PermGen out of memory errors. I have spent a good deal of time on this forum looking for solutions but have not been succesful. My environment is described in the log info below. EDIT: usually this seems to happen when switching to Design view while editing a class.

This is my current eclipse.ini:

-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
512m
-vmargs
-Xms250m
-Xmx500m

But continue to get out of memory errors with the following showing up in the log file:

This is definitely not a GWT Designer problem.

The problem is with the version of Eclipse (v3.3.1) you are using which has well known, documented, severe problems with memory usage (it ignores your eclipse.ini settings, so you are actually running with very little memory).

The fix is very simple...you need to immediately update to Eclipse 3.3.2 or 3.4 (both of which address the problem).

Searching for "OutOfMemoryError" should have uncovered the following earlier forum suggestion...

viewtopic.php?f=11&t=1925#p7009

if you are using any version of Eclipse 3.3.x prior to 3.3.2, you should immediately upgrade to 3.3.2 to avoid known memory usage issues.

Very good. Thank you. I'm upgradng Eclipse now.
