    * RECOMMENDATION:                                              *
    ****************************************************************
    After RRS is restarted, foreground applications (TSO) may not be
    able to connect to the queue manager because MQCONN/MQCONNX
    fails with MQRC 2025 MQRC_MAX_CONNS_LIMIT_REACHED.
    
    This problem is the result of the internal counts of active
    agents being decremented twice for the same agent and becoming
    negative.
    
    The queue manager has to be restarted to recover from this
    condition.
    

Problem conclusion

  • Internal counts of active agents are now incremented and
    decremented correctly.
