Hello.

Resently my PostgreSQL daemon died with:
IpcSemaphoreCreate: semget failed (No space left on device) key=5432015, num=16, permission=600

I figured out that the kernel is out of available semaphores,
I wanted to rebuild it but the problem is that the options
related to semaphores are not documented. This is the mission
critical commercial server so I don't want just to make assumptions.
Can you please tell me how these all enigmatic numbers are
properly choosed:
options         SEMMAP=31
options         SEMMNI=11
options         SEMMNS=61
options         SEMMNU=31
options         SEMMSL=61
options         SEMOPM=101
options         SEMUME=11

Thanks in advance, Andrey Novikov
