    This is a timing window where we requested a connection from
    CFW and by the time they call our callback to notify us that
    the channel is ready, we are already in the process of
    shutting down. The fix is easy, when the exception is
    caught, check to see if the Peer state is stopping or
    stopped and if so don't log the benign error.

    A NullPointerException is caught at
    com.ibm.son.mesh.CfwTCPImpl.ready (CfwTCPImpl.java:887) and is
    logged in a ODCF8601E message within SystemOut.log after the
    server has shutdown and has already logged its stopped message
    (WSVR0024I).
    

Problem conclusion

  • The Intelligent Management Peer-to-Peer Overlay Network has been
    altered to properly handle this condition when the process is
    being shutdown such that the NullPointerException is not
    incurred.
    
    The fix for this APAR is currently targeted for inclusion in fix
    packs 8.5.5.13 and 9.0.0.6.  Please refer to the Recommended
