MySQL root user

MySQL root user is meant for database administrators for administration task. Many times, I found it's being used as replication user and normal user for making connections to mysql database.

One of my clients did the same thing and later it was fixed.

110329 12:01:13 [Note] Slave SQL thread initialized, starting replication in log 'mysql-bin.003726' at position 850699172, relay log './poxxxx-relay-bin.000821' position: 11845356
110329 12:01:13 [Note] Slave I/O thread: connected to master 'root@xxx.xx.xx.xxx:3306',  replication started in log 'mysql-bin.003726' at position 850699172

It can be problematic in many scenario and mysql server restart can be required. It leads to below errors and don't allow connections to mysql database.

Too many connections
