Hi everyone,

First of all - thanks for all your feedback and suggestions. It has definitely helped to isolate where we should be looking, and what we should be looking for.

After some trial and error testing, we did find that during our nightly database back-ups, we were running out of space on the server. This caused somewhat of a chain effect which was congesting our mysql database, effectively shutting it down. Somewhere in that chain, the 'searchcore_text' table was trying to be optimised, and because of a lack of space, this couldn't complete and left the table corrupt.

We will obviously need to upgrade the space on our server - which is our next step.

The 'searchcore_text' was a contributor to our issue, but only because of the sheer size of the table. We will potential have to look at making this smaller without jeopardising the search function of our forum.

And then look at upgrading to the latest vBulletin.

Thanks again,
hilaryl
