    These messages show the connection was not cleaned up properly
    under this situation. The waiting threads can't get available
    connnections.
    

Problem conclusion

  • A NullPointerException is thrown while the web services engine
    is reading the transport headers from an http response message
    which was not available for some reason. Under this situation,
    the connection is not cleaned up properly, which caused the
    pool of connections to become full. Therefore, the waiting
    thread can't get an available connection.
    
    The web service engine has been corrected to properly handle
    connections under this situation.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.29, 8.0.0.6 and 8.5.0.2 .  Please refer to the
