	Oooh.  I ran into this one too on SCO OpenServer 5.0.4.  Samba allocates
something like 12-15 semaphores on startup (if I can remember the header
file right).  I'd go into your tunable parameters and change the amount of
semaphores to 50-60 or so.

	In another thread, I *do* have Samba running on 5.0.4, and I compilied it
from source, and didn't use the Skunkware version.  Skunkware seems to be a
bad distribution of it, as I never got Samba to work when using it. If
anyone needs help with a sucessful smb.conf, SWAT config or NT stuff with
SCO, mail me off the list.
