  * PROBLEM DESCRIPTION: Putting an event message to a remote    *
  *                      queue, with intra-group queuing enabled *
  *                      may result in a 0C4 abend in CSQMPOM.   *
  *                      This results in the intra-group queuing *
  *                      agent to go into a retry state.         *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When the intra-group queuing agent attempts to put an event
  message to a remote queue it puts the message into a 64-bit
  buffer. It then calls CSQMPOM to put the message to the
  destination event queue, this does not expect the buffer to be
  in 64-bit storage, resulting in only the lower 4 bytes of the
  address to be used, and an 0C4 abend in CSQMPOM. As the message
  was not successfully put, the IGQ agent goes into a retry state.
  

Problem conclusion

Temporary fix

Comments

• CSQMPOM has been updated to correctly handle event messages
  with the message data buffer in 64-bit storage.
