PMDF System Manager's Guide

Check whether messages are present under the PMDF message queue directory, /pmdf/queue/. Shell commands such as ls or the pmdf qm -maint utility's directory command can be used to check for the presence of expected message files under the PMDF message queue directory.

If the pmdf test -rewrite output looks correct, check that messages are actually being placed in the PMDF message queue subdirectories. If not, you can have a problem with file space on that disk.
