The 32 minutes past the hour got me thinking, and I think I've sorted the problem. There's a database cron job that runs four times an hour. Apparently it takes the database offline, tries to do a backup, then brings the database online again.
I've just stopped this process, so hopefully this won't happen again.
Cheers for the update Ash.
So, based on the above information, did anyone have issues at 21.32 tonight?
