Thanks for that, Tom. We were heading down the same path with our
thoughts and are at this moment moving the database onto a backup
server to see if we have the same problems. I will let you know how we
get on.

On a separate note I can say that, with regard to crashing on very
large IN clauses, we have seen such behaviour exhibited on several
servers.  However that is no longer a problem for us since we have
removed the badly-written queries!
