Login as root user to your MySQLd and run this statement: show variables like "max_connections"; Result would look something like this: +-----------------+-------+ | Variable_name | Value | +-----------------+-------+ | max_connections | 100 | +-----------------+-------+ Increase that number to allow more concurrent connections, for example run this statement: set global max_connections = 200;
To make this change permanent, locate your my.cnf file (often in /etc or /etc/mysql) and add this under the [mysqld] section: max_connections = 200 After a restart of the mysqld service this setting will be the new default.
Or maybe try a tool like mysqltuner.pl to find the optimised advised configuration setting for the max_connection limit: https://github.com/major/MySQLTuner-perl
