    jbpm flows stop executing

    Morten Hauch Newbie



      I will start to apologize for a vague error description - this is all I have....


      Running JBoss ESB 4.4 with the included jBPM 3.2.2 I have experienced "frozen" flows:

      All flows stop executing and the log is silence.

      The flows are started from ESB services. New flows hang in the start node. I can see that on-leave events are executed but the state is never changed to the following node.

      The flows use webservices through ESB services using the EsbActionHandler.


      I managed to get new flows to process by redeploying unchanged versions.

      I guess this indicates that threads for the "old" instances are in some sort of bad standing - however even a restart of JBoss did not help.


      Are there some symptoms I should be aware of - are there some causes that might be revealed by looking in the right places in the jmx-console?

      Are there some log4j categories that should be set to trace/debug?

      I will be very thankful if anybody could provide me with hints of what the reason to this can be?
