Error description

  • WebSphere MQ channels terminated unexpectedly with messages
    AMQ9604: Channel terminated unexpectedly
    and
    AMQ9208: Error on receive from host xxxxxx
    EXPLANATION: An error occurred receiving data from xxxxx over
    TCP/IP. This may be due to a communications failure.
    ACTION: The return code from the TCP/IP (read) call was 104
    (X'68').
    .
    The FDC's show that rriAcceptSess calls are failing in the
    amqrmppa process with a SIGSEGV and we are getting probe id's
    XC130003 and RM031101.
    The function stack for both FDCs shows:

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This problem may be encountered when attempting to connect to a
    queue manager which has channel auto-definition set (the queue
    manager CHAD attribute set to ENABLED). Users with channel auto-
    definition enabled are recommended to disable it if it is not
    required; or else to ensure a fix for this APAR is applied.
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    The SIGSEGV FDCs in amqrmppa show that function
    rriGetChannelDef (called from rriAcceptSess) invoked
    lpiSPIKernel which returned arcE_OBJECT_NOT_FOUND
    (it did not find the requested channel). Routine
    rriGetChannelDef should have returned a failure code, but it
    returned OK. This immediately leads to a SIGSEGV in
    rriAcceptSess. Very careful examination of the code of
    rriGetChannelDef reveals that there is a failure path out of
    this function whereby it fails to set its return code
    correctly.
    

Problem conclusion

  • Corrected the coding to ensure that all exit paths out of
    function rriGetChannelDef set a return code appropriately.
