    ****************************************************************
    When a ClearQuest Web CQRPC process reaches the 'Recycle
    Server Lifetime Limit', it is marked for termination by the
    CM Server. If the CQRPC process fails to exit, it will
    appear as hung in the process list and will run indefinitely
    if not terminated manually. Processes like that can and
    should be terminated to prevent them from consuming
    unnecessary resources such as CPU or Memory.
    

Problem conclusion

  • A fix is available in ClearQuest 7.1.2.9 and 8.0.0.5.
    
    A fix has been made to use a PERL script, called
    cqrpccleanup.pl, to address this issue. This script is run
    automatically by the CM Server periodically based on an
    MBean value cqrpcAbandonedProcessCleanupInterval.
    The script checks the PIDs of the cqprc processes that are
    running in CM Server and that are running on the machine
    itself. It terminates the processes that are not in the CM
    Server list and that have been up for at least 5 minutes.
