I get frequent crashes in Eclipse 3.5.2 / JDK 6 Update 21. The log file rapidly fills up with unhandled event loop exceptions. A typical stack trace looks like:

org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.OutOfMemoryError: PermGen space)
at org.eclipse.swt.SWT.error(SWT.java:3884)
at org.eclipse.swt.SWT.error(SWT.java:3799)
at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchr onizer.java:137)
at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.jav a:3885)

in eclipse.ini I've experimenting setting the MaxPermSize higher - it was at 256M and I boosted it to 384M with no effect.

I'm running XP Pro, SP3. I have no shortage of memory on my system and I run lots of other big, complex apps such as Visual Studio and Adobe Creative Suite with no unusual behavior.

This is ruining my productivity!! Thanks in advance for any help!

Can you move up to update 22 (the most recent)? I think there have been fixes in the interaction with Java and Eclipse that that make the permgen problems go away.

Alternatively (or additionally) you might consider to switch to Eclipse
3.6.x. Here, the Eclipse implementation has changed their VM recognition
logic.

Our entire group (about 15 engineers and designers) would have to switch if we changed versions of Eclipse or Java.

Is there any fix that doesn't involve changing versions of Eclipse or Java?

If we did change am I correct in assuming that updating Java would be the least disruptive of the 2 choices? Does it have a high likelihood of fixing the problem (Francis said he "thinks" it might fix it)?

I don't know.

I assume so.

I'm quite sure that it will fix the problem.

Maybe you've come across bug #319514.
You have to re-download and re-install JRE 1.6.0_21 or switch to 1.6.0_22.

Otherwise have a look at:

That is about 3.32, I'm running 3.52.

In any case I volunteered myself to be my group's guinea pig for update 22 and so far it seems to be working OK so I think that will be the preferred solution. Thanks to everyone who contributed!

I've updated that wiki page to eliminate the references to 3.3, as most
of the material applies to all versions.
In particular, the very first section was what I was pointing you to
( http://wiki.eclipse.org/FAQ_How_do_I_run_Eclipse%3F#Oracle.2 FSun_VM_1.6.0_21_on_Windows);
that part contains info about several options for resolving the problem
you were experiencing.
