Error description

  • WebSphere MQ listener process fails to start with an AMQ9255
    error reporting rrcE_LISTENER_ALREADY_RUNNING.
    The queue manager error logs will show a sequence of
    "AMQ5026: The Listener 'xxx' has started, followed shortly by
    "AMQ5027: The Listener 'xxx' has ended " messages.  A trace of
    runmqlsr will show the AMQ9255 error as follows:
    04:57:43.467556    1234.1   :  ----}! socket  rc=Unknown(11)
    04:57:43.484936    1234.1   :   ----{  rrxError
    04:57:43.484996    1234.1   :  RetCode = 20009255
    

Local fix

  • A graceful closure of the listener using endmqlsr(or similar
    
    command) prior to reboot or recycling of the queue manager
    would be a temporary workaround
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    WMQ 7.1 users having multiple listeners and recycling them
    frequently may encounter this issue.
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    While starting a listener WMQ generally checks and tidy up the
    old socket files. But in some special cases where remnants of
    the previous listener socket files are sill active there could
    be problem where WMQ might think a listener is already running.
    

Problem conclusion

  • Code changes have been carried out to clean up the old socket
    files before starting a listener.
