MySql down and up after the replication function is activated

I installed ispconfig as Control Panel.
I configured the replication function on MySQL, then I get the following message in each 30 minutes in Master. ( may be from the momit service)

Warning: service mysqld not running (server: xyz.com)!
Message generated at October 31, 2007, 14:30.

Does this message mean working normally?

 

What's the output of

Code:

netstat -tap

?
Please log in to MySQL:

Code:

mysql -u root -p

and run

Code:

SHOW SLAVE STATUS;

What's the output?

 

netstat -tap

Code:

MySQL isn't listening on all interfaces. What's in your my.cnf?
