APAR status

  • Closed as program error.

Error description

  • There is a condition when a mail sever goes does down can cause
    the Notes Traveler server to have the # of DB connections to
    continue to grow and threads continue to run for a long period
    of time.
    
    The code will fix the resource contention issue where threads
    get stuck waiting on each other.  The work around for the
    problem is restart Notes Traveler.
    

Local fix

  • Restart Notes Traveler task
    

Problem summary

  • Some customer reported slow sync times and Red Status messages
    on the server for long running threads.  In addition the
    customer may see 503, server busy messages due to maxed out
    database connections.
    
    This problem was actually triggered when a member of a mail
    cluster changed in status, for example was rebooted.  The
    actions to record the state change of the mail server were being
    single threaded to the Notes Traveler database thereby
    artificially backing up the Database connections.
    

Problem conclusion

  • The Notes Traveler server was updated to handle this update in
    parallel and not backup up threads for a minor update.
    

Temporary fix
