GMF and out of memory error [message #89903]

I am experiencing a lot of "out of memory errors" when using GMF. Has
anyone else noticed this? At least once an hour I have to shutdown my
workbench. I have the heap monitor open, and it doesn't seem like it is
using a lot of memory (about 60M of 1/2 Gig I gave Eclipse). I am using
Eclipse M4 with GMF M3 (because GMF M4 didn't seem to pass it's
regression tests).

cheers,
ian

Just so that you don't think you're the only one, I've also experienced a
lot of issues with GMF and memory. My overall Eclipse stability has
lessened, and Eclipse crashes more often than it used to. As to how to deal
with those, I'll have to let someone else weigh in.

I noticed the following while creating an *.ecore diagram during my tutorial
update for 2.0 M4:

Error
Sat Jan 06 09:18:45 EST 2007
Ignoring provider
org.eclipse.gmf.runtime.diagram.ui.providers.internal.Diagra mIconProvider
since it threw an exception or error in the provides()
method

java.lang.OutOfMemoryError: PermGen space

To get around it for now, I added the following to my eclipse.ini file:

-XX:MaxPermSize=128M

Best,
Rich

My eclipse also very often crashes with "out of memory errors".

In my opinion it happens usually when I working on my genmap and
regenerate my diagram few times.

I have GMF M3.

Hello Wiktor,

Are you using custom templates (jet)? It could be a known problem of PermGen
limit - dynamic JET templates does not unload generated+loaded classes..

Thanks Rich, I will try that. If the problem persists I will keep you
updated.

I also had GMF and Mylar running and Eclipse would just "die". Not out
of memory, the VM would just no longer be running. There wasn't even
anything useful in the log. This problem went away when I disabled
Mylar (I still had out of memory errors), but I have been using Mylar
(without GMF) for almost a year and this never happened.

I assume GMF is going to be part of Europa, (so is Mylar), so I will
keep testing this setup. If I find anything useful I will let you and
Mik (Project lead for Mylar) know.

cheers,
Ian

So, you probably do not use it. ;-) There is a special parameter in .gmfgen
model allowing dynamic templates (off by default)
