PM96826: BROKER WEB SERVICE RETURNS INTERNAL ERROR CODE 2019

APAR status

• Closed as program error.

Error description

• An HTTP client invoking a web service that is hosted on
  WebSphere Message Broker V8.0 for z/OS intermittently receives a
  SOAP fault message reporting an internal error. The problem only
  starts to occur after the broker has been processing HTTP
  requests for a period of a few hours, depending on the message
  load. The fault string reported is normally either:
  "An internal error has occurred: 2 2019 in putToInputQueue"
  or
  "An internal error has occurred: 2 2019 in getFromReplyQueue"
  
  The codes "2" and "2019" represent the completion and reason
  codes returned from the WebSphere MQ API calls MQPUT and
  MQGET, suggesting that the calls failed due to reason
  MQRC_HOBJ_ERROR.

  PROBLEM SUMMARY:
  An HTTP client invoking a web service that is hosted on
  WebSphere Message Broker V8.0 for z/OS using the broker-wide
  HTTP Listener intermittently receives a SOAP fault message
  reporting an internal error. The problem only starts to occur
  after the broker has been processing HTTP requests for a
  period of a few hours, depending on the message load. The
  reported errors indicate a problem obtaining a queue handle used
  for putting messages to or getting messages from the WebSphere
  MQ queues used internally by the HTTP Listener process.
  Listing the open queue handles owned by the HTTP Listener
  process shows the number increasing over time until no more
  can be allocated.
  
  
  
  There are a number of resource name changes between WebSphere
  Message Broker and IBM Integration Bus Version 9.0. For

  tools.mft.doc/bb23814_.htm
  

Problem conclusion

• The HTTP Listener process on z/OS no longer leaks queue handles.
