Greetings,

   I am trying to bet a BSDI binary (a database) to run on 2.2.5 but when I
try to access the database server it crashes with an error to semop(), then
semctl() error 22.  I did a ktrace and kdump to see what might be going on,
but I really am not sure what I'm looking at.  I have options SYSVSHM
SYSVSEM SYSVMSG set in my kernel, is there anything else I should check?  I
noticed *many* options for semaphores in the kernel LINT file, but I have
no idea where to start.

   Any info, pointers, man pages to read, etc. would be greatly
appreciated.  Also, how compatable is FreeBSD's semaphores to BSDI's?  Then
again, I think BSD4.4 borrowed semaphores from SVR4?  Yes, no?

Thanks,
Matthew Hagerty
