What type of record locking does FM use - optimistic or pessimistic?

Please point me at sources of wisdom on record locking.... had a lockup today - ended up restarting the hardware to clear it ... if there's semaphores or other pointers I can look at, I really would like to know how to find them.

Thanks in advance.

FileMaker itself uses Pessimistic locking. However, when writing to the other databases with the new ESS feature it uses optimistic locking.

I had to check whether you were joking or not. You weren't. :)
