APAR status

  • Closed as program error.

Error description

  • The file logger (used for NTSActivity, NTSErrors, NTSAudit and
    NTSUsage) may get into a thread deadlock if multiple threads are
     trying to log an entry that hasn't already been formatted (most
     log records are already formatted, so this situation should be
    quite rare).
    
    The change to the formatter that exposed this possible thread
    deadlock went into Traveler 9.0.1.16, so it could be hit any
    time after that; but given how long that has been and we have
    had only 1 customer report the issue as of 9.0.1.19, the chances
    of this issue are small.
    

Local fix

  • Restart Traveler.
    

Problem summary

  • Thread deadlock could cause Traveler server to hang.  This is an
    uncommon timing issue.
    

Problem conclusion

  • The IBM Traveler server has been updated to handle this scenario
    correctly.
    

Temporary fix
