mysql restarts

    I'm running Plesk 7.5.4 (Linux). I've noticed that every now and again (3 or 4 times a day?) mysql restarts. The message in the mysqld.log file is below.

    I can see no reason for this. I've run mysql on other (non-Plesk) servers and it has always run 24x7 without restarting.

    I've already reinstalled the server once and have not changed my.cnf. Everything (including the databases) seems to work ok.

    Any ideas what might be happening?

    Are you running watchdog? If so then dump it, alot of other people have said it restarts services for no apparent reason.

    Well, I wasn't running the watchdog but installed it later as I thought it might help!

    In the end I upgraded mysql to version 4 (from 3) and the problem seems to have gone away (so far!).

    I've still no idea what was causing version 3 to restart.

    Hmm, odd. I am using mysql3 and it is solid.
