Problem summary

  • ****************************************************************
    * USERS AFFECTED: 01.RDz users whose server is v9.1.1.1 or     *
    *                    higher                                    *
    ****************************************************************
    * PROBLEM DESCRIPTION: 01.RDz server gets frozen in a heavy    *
    *                         load environment.                    *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    01.Thread pool processes in RDz server are created and stopped
       in a heavy load environment and an array to manage each
       thread pool process grows according to the number of the
       active thread pool processes. When a thread in RDz server
       tries to access the array entry for a newly created server,
       ArrayOutofBound Exception could occur in a heavy load
       environment and that makes the thread fall into an infinite
       loop.
    

Problem conclusion

  • 01.RDz server code is updated to allow the internal process
       table accessed even if a new thread pool process is not
       completely started.
