Not 100% sure, but I thought that your loop will not work if the message on
top of the queue is not falling into your range, and the message would
remain on the queue (due to 'NOREMOVE' flag), and will
ssage
ID range.

to properly help we'd really need to have an understanding of what your wait
loop is waiting for, and how its waiting..
you are most likely causing a deadlock where the handle message is passing
it to something else that could be waiting for your wait to complete. The
handle message could be forci
ld well be outside of your
message ID range.
