Thanks... I did come across one or two items on the list but none seemed 
to match the symptoms I'm seeing. The problem occurs without any 
restarts taking place so seems not to be the same as the problem you 
mention. It sometimes will works for many days and then fall over - no 
restarts, and plenty of memory left.

I've allocated more than enough memory to ensure SHM never runs out so 
I'll try the shm_only option and see how that goes.

Cheers,
Andy.
