I'm using the JBPM 5.3 installer running on JBOSS 7
I run the evaluation process a number of times and the processes complete as expected.
Intermittently the task service apppears to complete the human tasks however the transition to the next activity does not occur.
In the H2 DB the task status is COMPLETE however it appears the task is still active.
I have not changed the evaluation process and I have experienced the same issue with a simple process which consists of 1 human task.
Any assistance greatly appreciated.
It looks like process engine lost connection to task service (that is done via work item handler dedicated to user tasks). Do you see anything in logs? Any exception related to task service? Does restart of the server help in anyway?
