Subject: msgrcv failures under Xenix - invalid qids ?

Why does a msgrcv call in a Xenix program suddenly fail with errno=EINVAL
after it has successfully executed many times?  Is it possible that some
other queue has filled up, exhausting the available message headers? Could
this cause a previously valid qid to become invalid?
