MySQL restart - all sessions cleared

[n000b]

I have a vBulletin installation which, when MySQL is restarted on the server, all user sessions are cleared - all users who haven't selected "Remember Me" are logged out, and everyone disappears from the "Who's Online?" box.

Is this normal behaviour, or is something wrong? I would have thought that the sessions would still work if MySQL is restarted.

Yes that is normal because sessions are kept in memory so when you restart MySQL (which you should never do when your forums are on) will wipe out those sessions.
