Hello,

Make sure that MySQL is running and you can access it from the command line:

# mysql -uadmin -p`cat /etc/psa/.psa.shadow` psa

If it works, try to increase maximum connection number for MySQL server. By default the number of simultaneous connections is limited to 100, if MySQL is highly used on your server, you need to increase this limit in /etc/my.cnf in section [mysqld]:

[mysqld]

set-variable=max_connections=200

Then restart MySQL.

# /etc/init.d/mysqld stop
# /etc/init.d/mysqld start
