APAR status

• Closed as program error.

Error description

• When a call is terminated, a CANCEL is not sent to the
  far end until after 180 seconds.  Trace shows that a ProxyTimer
  is being created for the 180 seconds, and when this expires,
  the CANCEL is sent. However, the parallel proxy scenario is
  not being used.

  ****************************************************************
  Incoming Cancel request for a request that was proxied and is
  not handled by the server is causing a NullPointerException
  since it does not have an application attached
  

Problem conclusion

• When a Cancel message arrives for a request that does not
  belong to the server the server is not trying to find the
  approriate application. This has been corrected.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.0.0.2.  Please refer to the Recommended Updates
