    ****************************************************************
    The OMEGAMON for IMS classic address space uses an excessive
    amount of CPU time when the ATF feature is active.  This
    is due to a logic error that causes a loop when managing
    the queues of ATF trace data.
    

Problem conclusion

  • Corrections to the ATF trace data queue manager were made to
    eliminate the error causing the loop.
