Is someone trying to put qmail's message queue on an NFS share ?
This is an absolute no-no, if you are interested in reliable mail delivery
(and if you are not, why use qmail ?)

5. Handling queued mail (qmail-send, qmail-clean)
The queue directory must be local. Mounting it over NFS is extremely
dangerous---not that this stops people from running sendmail that way!
Diskless hosts should use mini-qmail instead.
