PH41928: 503 RECEIVED WHEN SERVER IS STOPPING, NOT ABLE TO RETRY REQUEST

APAR status

• Closed as program error.

Error description

• During a POST request process, a 100-continue response might
  return to a client so that the actual request data could be
  sent in. If the WebSphere Application Server is stopped during
  this 100-continue process, the subsequent request with actual
  POST data might result in a 503 response, and the request é ádat
  would be lost.

Problem conclusion

• The channel code is updated to detect if the server is stopping
  and returns a 503 response as early as possible.
  
  The fix for this APAR is targeted for inclusion in fix pack
  9.0.5.12 and 8.5.5.22.
