OK, so I think you're hitting the "kern.ipc.semmns" limit of 60 - that does match the output from ipcs (3x17 for postgres, 3x3 for bb - Hobbit
- gives 60. So some of the Hobbit ones are missing).
I'll have a go at google with your info...
This is the best one I've found yet. The kern.ipc.sem* sysctl settings are "read-only", so apparently they can only be modified upon a reboot, by listing them in /boot/loader.conf:
