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 wpub1@net-link.net
