"Guvnor stability"

--------------------------------------------------------------
Hi, I'm trying to understand the source of an unstable behavior in Guvnor.
Yesterday I was editing the (only one) process in the repository.Then I suspended my
laptop.
Today, after resuming, I cannot proceed, since:
- drools-guvnor, upon trying to list processes, says "Sorry, a technical error
occurred. Please contact a system administrator". No process shown.
- console, upon trying to list processes, waits for a while then it reports a request
timeout. No process listed.
Log is:

Then I stopped/restarted jboss (ant stop.demo/ant start.demo). Same result afterwards.
Is there any other log to look at ? Any other action I might take ?
Thanks.

To provide further info, I looked at jboss log file server.log, after restarting it and
running the console to get a process list.
I see a couple of errors:
2011-08-05 09:24:40,499 INFO [STDOUT] (http-localhost%2F127.0.0.1-8080-5) ERROR 05-08

PackageDeploymentServlet threw exception
java.lang.NullPointerException

...
But the funny point is that now, after an hour of attempts, a process appears both in
drools-guvnor and the console !
But in drools-guvnor is my new Test process, while in console is Evaluation.

jBPM-console currently looks for assets in the pkg file of the Guvnor defaultPackage only
(we are working currently on expading the lookup to all available packages in Guvnor).
Unless you build your package in Guvnor after making changes, console will not be able to
see your changes. It could be that you have not built your package and the no-longer
existing Evaluation process is still present in the pkg?
Both Guvnor and jBPM-console are webapps and have a session timeout. After a long absence,
you would need to re-log back into guvnor (I think the error "Sorry, a technical
error occurred. Please contact a system administrator" is indicating this, you would
more accurate error in the server log). This is probably also the reason for the other
errors but I am not sure without seeing the entire stack of the logs.
Hope this helps.

I'm afraid it isn't so easy.
After the weekend (and yes, logging in again) I cannot reopen my test process. I got an
out-of-memory server error, and the jboss server.log reported below (I apologize for the
long report).
Finally I stopped/restarted jboss then guvnor, my test project is there but totally
empty.

The overall sequence can be reproduced, by creating a process such as:
start/initial task/split xor gateway/two branches, one task each/join gateway/final
task/end.
No properties or names. Save and close. Open again, then the jboss outOfMemory error
appears.

I'm not able to reproduce your
Caused by: java.lang.OutOfMemoryError: GC overhead limit exceeded
error. IIRC in these cases you should make sure your heap is big enough and possible also
try to turn off the overhead feature with
-XX:-UseGCOverheadLimit
