Running FB classic 2.1.2.18118 on Mandriva 2009 with an unmodified
firebird.conf.

I have had a corrupted database, and prior to this firebird.log contains the
"Fatal lock manager error: semaphores are exhausted" message. The system would
only have had one or two users connected at the time, so can someone please
tell me what operations cause a semaphore to be used? For example is the
number of semaphores used affected by the number of active transactions, and
does running nbackup use any semaphores?

Also, does this message mean that FB has used all of semaphores as determined
by LockSemCount (default 32 I assume) or does it mean that Linux has run out
of semaphores?

I'm trying to determine if I need to increase the value of LockSemCount, and
if so, what should I increase it to.
