I don't know if this indicates that a mailbox can't be located, or
allocated, or there aren't enough available. If you simply need more
mailboxes, you may be able to increase the number allocated. I don't
know about Esix, but with ISC Unix this number is AHA_NUM_MBOX which
is defined in /usr/include/sys/aha1540.h.
