Problem summary

  • ****************************************************************
    * USERS AFFECTED:  Session Initiation Protocol (SIP) users     *
    *                  of IBM WebSphere Application Server V7.0    *
    *                  and V8.0                                    *

    * PROBLEM DESCRIPTION: Outbound messages are dropped.          *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The problem occurs when the SIP container is sending out
    messages over a connection that it created out, and then it
    closes this connection. In some edge cases it closes the
    connection before having sent all messages in the outbound
    queue.
    

Problem conclusion

  • With this fix, the SIP container closes the connection in two
    steps. First, it flags the connection as "closing down". In
    this state, messages that are already queued for delivery are
    processed, but no new messages are queued. Then, only after the
    last message is removed from the queue and sent out, it
    safely closes the connection down.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.23 and 8.0.0.3.  Please refer to the
