  • Closed as program error.

Error description

  • The client had a failure, and at the debug loglevel there would
    be a report that plugin received an incorrectly formatted
    response.
    The appserver maybe in the process of sending data after web
    server plug-in has timed out a request. This data could cause
    failures when the socket is reused on a new connection.

    ****************************************************************
    The reuse of a connection from a different client may cause
    problems for the current connection if the previous client
    connection ended as a result of a time out.  In this
    situation, erroneous data was resented to the new client
    causing a failure with their transaction.
    

Problem conclusion

  • The plugin has been updated so that it will not reuse
    connections that had a time out from the client.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 7.0.0.45, 8.0.0.14, 8.5.5.13, 9.0.0.5.  Please refer
