Greetings. We are trying to diagnose an intermittent problem: while one branch of a Fork is in a wait state, the other branch's child token continues through the join and continues executing subsequent process steps. | Fork | / \ | Task Process Step | \ / | Join | | | <more steps> | The first branch is waiting at the task node. The second branch executes the process step, hits the join, and continues executing steps as a child of the root token. The root token remains at the Fork node as expected. Any theory on what might be causing this behavior? It only happens once in a long while, and we have no way to reproduce it in a test environment. Using jBPM 3.1.2 with some bug fixes from newer versions. Thanx in advance for any thoughts. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4255314#...
