2499 (09C3) (RC2499): MQRC_MSG_HANDLE_IN_USE

Explanation

A message property call was called (MQCRTMH, MQDLTMH, MQSETMP, MQINQMP, MQDLTMP or MQMHBUF) specifying a message handle that is already in use on another API call. A message handle may only be used on one call at a time.

Concurrent use of a message handle can arise, for example, when an application uses multiple threads.

Completion code

MQCC_FAILED

Programmer response

Ensure that the message handle cannot be used while another call is in progress.
