Yes, this is pretty much what I was saying. 

Please review attached patches (providing two options):
opt1 - utilizes end method of ExecutionImpl to clean up
opt2 - removes reset of subProcessInstance in signal method of SubProcessActivity

I have not experienced any problems with db constraint violations. But I agree that if that will pop up that solution is not an option any more.

Please review the patches and let me know your comments.

I tried to upload them to jira but seems like it is not fully available at the moment, upgrade is on its wa.
