-- Yes, I do have SYSV stuff enabled in my kernel:
options         SYSVSHM                 #SYSV-style shared memory
options         SYSVMSG                 #SYSV-style message queues
options         SYSVSEM                 #SYSV-style semaphores

Shell access can be made available if it helps the team track this one down.

Lew Payne
