To view the discussion, visit: http://community.jboss.org/message/555471#555471 -------------------------------------------------------------- I have a similar issue and I think there is a race condition between the DispatcherThread that handles the execution of async Messages/Jobs and the main-Thread. Both alter data in the JBPM4_JOB table, I think this is what is going on: 1. main-Thread is running along, minding his own business and creates a hibernate-Session 2. DispatcherThread wakes up and also creates a hibernate-Session accessing data in the JBPM4_JOB table 3. DispatcherThread did its work and removes the Job data from the JBPM4_JOB table 4. main-Thread ends an execution and deletes the execution related data from the JBPM4_JOB table, since the same data have been altered by different session there is an exception at this point -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/555471#555471] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
