PK82831: SA03 ABEND DURING SERVER STOP PROCESSING AFTER REPLICATION WAS ENABLED.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When STOP is issued for the application server, the servant
  comes down, but controller abends with SA03.  This behavior was
  triggered by configuring memory-to-memory session replication.
  
  The dump of SA03 shows 8 threads still up in the controller.
  The last one in the list (ip summ format) is the one that caused
  the problem.
  
  Based on a console dump taken right before STOP was issued, the
  last thread in the SA03 dump was a daemon thread and had the
  following traceback:

  DRS uses a daemon thread that waits for incoming requests.
  The thread is interupted during the shutdown but the thread
  resumes waiting in the while loop.
  

Problem conclusion

• A flag has been defined that is set when the runtime component
  shutsdown the DRS service. This flag is checked during each
  loop iteration and exits if a shutdown has been initiated.
