      JBPM 5.1 seems unstable on the concurrent request happen. It seems a critical issue when we using persistence humantask on JBPM5.

      Attachment are our code , normal logs and error logs.

      We found that the the error logs missing two line as the screenshot (MissingOneUpdateInErrorLogs.jpg) shown. After that, the task cann't be finished by the next steps.Not sure it is cause our code or the JBPM API. There are not any error reported from JBPM API.

      Please help us for analysis this problem, it would be nice if you can hlep us to fix those error data,no metter by DB update or JBPM API.

          And I found that the error seems happen jboss-5.1.0.GA on  Windows Server 2003 R2 , We had tried ,the jboss-5.1.0.GA Server on Windows7 works fine to us. We had use the same source code ,workflows and Database on our testing.

           

          BTW we also found that the JDK version aslo a factor on this problem,on the  jboss-5.1.0.GA on  Windows Server 2003 R2 ,the different JDK version will have different error rate.  under the JDK1.6.0_13, we have nealy 10% error, and under JDK1.6.0_30, we only got less than 5% error in the same stressing.
