Hi all, I would like to collect experience/comments on this issue, occurring at random but very often in my case.
I have just two simple processes in Guvnor, 8 nodes each. One is BPMN2-ExclusiveSplit and the other is very similar.
The defaultPackage has been successfully built.
I can either run the Console to list processes, or I can run the Designer to view process definitions, edit them and rebuild the package.
But as soon as I switch from an application to the other, soon I get a jboss error as reported in the subject.
>From that point on there's no way to proceed until I stop/restart jboss. I tried to logout from both application and to reenter: no way.

I also tried to set -XX:-UseGCOverheadLimit, without any success. Things get blocked soon because of "java.lang.OutOfMemoryError: Java heap space".

As an example of a failing sequence:

- start the designer, select defaultPackage, list processes.
- open both processes.
- from the browser go to the rest url /gwt-console-server/rs/process/definitions, getting:
