Local fix

Problem summary

  • The agent terminated because it had received a recovery message
    from the destination agent before it had received the response
    to the initial transfer negotiation message.  This can occur
    when messages are received from IBM WebSphere MQ out of order.
    
    USER AFFECTED:
    All
    
    PLATFORMS AFFECTED:
    All
    

Problem conclusion

  • The code has been altered so that it handles out of order
    messages from IBM WebSphere MQ.  The agent ignores the recovery
    message continues to wait for the initial transfer negotiation
    response message.
