Group,
This problem was finally resolved by altering the application. It
was in fact coded to OPEN, GET, CLOSE for every message. When this was
changed to a do/while loop things started behaving much better. Thanks for
all of your feedback.

That most commonly happens when the application closes the queue before it
is empty. Qmgr sees IPPROCs drop to zero and since there are still messages
on the queue it fires another trigger to process them.
If you want to "trap" trigger messages in the initq, write your own
quick-and-dirty "trigger monitor" that simply opens the intiq for input, but
doesn't destructively read the messages.
