[jboss-user] [jBPM Users] - Fork branch runs through Join node

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.
