Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users using MQ queue managers with Accounting monitoring
    enabled.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    If application ends without disconnecting then an implicit
    MQDISC is issued to free resources. As part of MQDISC accounting
    data for the connection is put to the accounting queue.  A
    coding error caused this MQPUT operation to fail as some
    internal resources had been prematurely freed before the MQDISC
    operation began. The absence of these resources results in FDC
    records with ProbeID  KN170060 , KN802010.
    

Problem conclusion

  • The MQ code is modified such that the required resources are
    freed after the thread disconnects, and the accounting data has
    been put to the accounting queue.
