Error description

  • A WebSphere MQ Managed File Transfer V7.5 file transfer is
    started and then the
    destination agent is stopped immediately while the transfer is
    in flight.
    After a few minutes restarting, the destination agent does not
    continue the transfer causing the transfer to enter into a
    stalled state.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of WebSphere MQ Managed File Transfer v7.5
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM SUMMARY:
    When a transfer was started and the destination agent process
    was immediately stopped or killed before the transfer completed,
    then the transfer entered a recovery state when the transfer
    acknowledgment timeout was reached (transferAckTimeout *
    transferAckTimeoutRetries).
    
    Once the transfer was in the recovery state, if the
    destination agent was then restarted, then the transfer did
    not continue as expected. The transfer progress would then
    change to a 'stalled' state.
    
    If a new transfer was started then this would run and also
    restart the 'stalled' transfer. If no new transfer was started
    then only restarting the source agent process would allow the
    'stalled' transfer to continue.
    

Problem conclusion

  • The WebSphere MQ Managed File Transfer logic has been modified
    to resolve the issue and allow a transfer that has entered
    recovery state to continue automatically once the destination
    agent has restarted.
