IC79904: WEBSPHERE MQ EVERYPLACE V2.0.2 (MQE) APPLICATION GETTING 'MQEREASON_INTERNAL_ERROR' ERRORS

APAR status

• Closed as program error.

Error description

• MQe application frequently gets the following error:
  [11-11 15:26:30.860] MQERETURN_QUEUE_MANAGER_ERROR(0x400000)
    MQEREASON_INTERNAL_ERROR(0xE)[11-11 15:26:30.860]
  .
  In some instances, the MQe application was unable to send
  message to the MQe Gateway because of this error.
  

Local fix

Problem summary

• After the channel timeout on the server side the client has
  tried to put message and failed with Channel error. This has
  caused the channel issue.
  The MQe trace shows the channel issue:
  ----------  [1320983204754] (4060) {Channel ID}
  ----------} [1320983204754] (4060) MASTER_CHANNEL_CHECKRETURN
  (rc= MQERETURN_CHANNEL_ERROR), (erc= MQEREASON_CHANNEL_ID)
  

Problem conclusion

• It was the responsibility of the client to free the old invalid
  channel and create a new channel. The code for this is already
  available in the WebSphere MQ Everyplace C Native Code base but
  it does not get invoked in one of the cases. The fix for this
  issue ensures that a new channel is created by the WebSphere MQ
  Everyplace client when there is a channel timeout.
