<div class="jive-rendered-content"><p>Hi all, I would like to collect experience/comments on this issue, occurring at random but very often in my case.</p><p>I have just two simple processes in Guvnor, 8 nodes each. One is BPMN2-ExclusiveSplit and the other is very similar.</p><p>The defaultPackage has been successfully built.</p><p>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.</p><p>But as soon as I switch from an application to the other, soon I get a jboss error as reported in the subject.</p><p>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.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I also tried to set -XX:-UseGCOverheadLimit, without any success. Things get blocked soon because of "java.lang.OutOfMemoryError: Java heap space".</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>As an example of a failing sequence:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>- start the designer, select defaultPackage, list processes.</p><p>- open both processes.</p><p>- from the browser go to the rest url
