You keep writing about this.... if it is a dedicated server, I strongly suggest to find out where you mysql errors logs are and check them out yourself. Or, open a shell and find out how long mysql has been 'up' so you can find out if it has recently been restarted. If it is restarting itself, it is because of a setting somewhere that is triggering the restart. It may be in your my.cnf file. However, you need to read your mysql error logs in order to find out if it really is restarting itself and what the reason is. If you don't know that, then you can't fix it.
