PM96586: SYSTEMFIRSTFAILURE LOG ERROR CONTAINS THE "WAITALL FOR MULTIPLE HANDLES ON A STA THREAD IS NOT SUPPORTED" ERROR

APAR status

• Closed as program error.

Error description

• Calls to the .NET Client Connect() API will generate this
  error in the SystemFirstFailure log when 1) multiple catalog
  servers are passed to the Connect() API, and 2) the calling
  thread belongs to a Single Thread Apartment (STA).  The
  following exception is contained in the SystemFirstFailure log.

  * PROBLEM DESCRIPTION: The SystemFirstFailure.log              *
  *                      file contains the error: WaitAll for    *
  *                      multiple handles on an STA thread is    *
  *                      not supported.                          *
  ****************************************************************
  * RECOMMENDATION:  This failure can be ignored as the          *
  *                  subsequent connection to the catalog        *
  *                  server fails if the client and server       *
  *                  configurations are incompatible.  However,  *
  *                  the error information provided in this      *
  *                  scenario is more generic compared to        *
  *                  the error information reported during the   *
  *                  connection probe.  To remove this entry     *
  *                  from the SystemFirstFailure.log file and    *
  *                  receive more detailed error information     *
  *                  about incompatible client-server connection *
  *                  configurations, apply this fix.             *
  ****************************************************************
  Calls to the .NET Client Connect() API generate this
  error in the SystemFirstFailure log when 1) multiple catalog
  servers are passed to the Connect() API, and 2) the calling
  thread belongs to a Single Thread Apartment (STA).
  

Problem conclusion

• The transport probe logic has been updated to support STA
  threads.
