We are running MQ version 5.3 on ZOS. We had a situation where a queue was left open for input because of a program crash. The program never got to do a disconnect. This program was a Natural program running under COM-PLETE. So basically that queue was left open for input for two days. Today someone ran a Natural program and put a message to a queue. The message on the queue had the userid of the person who's program crashed on the user identifier. Also the queue that was left open for input was no longer open. I think what happened was when the person ran a program today, he picked up the handle that was left connected from the previous program crash and ended up using that userid and then when he disconected it closed both queues. How is it possible that MQ grabbed the same handle, when one was open? The program running runs as a server program to the queue manager and connects with MQCONN, which defaults to a nonshared handle.
Thanks,
Gary
