Hi,
On my Fedora server Mysql 5.0 is restarting itself in every 2-10 mins.
It restarts much often when the server load is high.
No error message in log. Just this:

070115 23:32:11 [Note] /usr/sbin/mysqld: Normal shutdown
070115 23:32:13 InnoDB: Starting shutdown...
070115 23:32:20 InnoDB: Shutdown completed; log sequence number 0 53791979
070115 23:32:20 [Note] /usr/sbin/mysqld: Shutdown complete
070115 23:32:21 mysqld ended
070115 23:32:54 mysqld started

Here is my.cnf file
[mysqld]
safe-show-database
socket=/var/lib/mysql/mysql.sock
log-error=/tmp/test.log

[client]
socket=/var/lib/mysql/mysql.sock

somehow a mysql.sock already exists in tmp folder.

can anybody help me to solve the problem?

Thanks in advance
