Automatic logout

I’ve a website that runs in Single Server mode, and has an idle session timeout of 360 minutes. Long before this though tt seems to log itself out somehow, and when I try to access a page again, I get:

Http Status Code: 404

Reason: File not found or unable to read file

When this happens I have to close every browser session, and mail (for I use Mozilla) until I can log in again.

Am I doing something obviously wrong? If it logs itself out because it’s timed out, surely a log in should fix it, or is there some session running somewhere that isn’t keeping a proper track. It’s really annoying!
