Now when I access PHPlist it often shows this error: Fatal Error: Sorry, the server is currently too busy, please try again later. When I am trying to access phpMyAdmin, it shows me a #1040 error. Output of my PHP scripts which run through cron jobs shows: PHP Warning: mysqli_connect(): (HY000/1040): Too many connections I am using the LAMP stack on the server with phpMyAdmin; the top output in terminal shows mysqld using 100-130% CPU. When I am trying to troubleshoot this problem I got some clues: Increase max_connection variable : I am using 200 (100 by default) Open table cache: 512 (400 by default) There are lots of variables to set but I can't determine what specific ones, I am getting some reference from: too many connections and http://dev.mysql.com/doc/refman/5.5/en/table-cache.html But according to my usage how to increase memory and what is the maximum memory difficult for me.

- Error #1040 - Too many connections" when you work in the phpMyAdmin interface. This probably is https://thomas.vanhoutte.be/miniblog/phpmyadmin-error-1040-too-many-connections/ something you don't have to worry about that much. It is likely a temporary issue with your database and reloading the page should solve the issue. However, https://kb.plesk.com/en/769 if this error is one you see often it might be time to take action.SSH into your server and execute this command;sudo nano /etc/my.cnfWe will edit the too many my.cnf file which can be found in the /etc/ directory of your Linux webserver. Change the value of max_connections to something higher than you have now, such as 250: max_connections=250Alternatively, you can also change this value through MySQL.mysql> SET GLOBAL max_connections = 250;Now, restart the MySQL database so the changes take effect:/etc/init.d/mysqld restartphpMyAdmin too many connections - Error #1040 - Too many connections was last modified: December 13th, 2014 by Thomas

New connections to the server cannot be established at this time. Resolution There are two ways to solve this issue. The first is to increase the connection limit, and the second one is to determine the cause of the "Too many connections" error and use that information to lower MySQL server usage. The MySQL server status can be checked using the mysqladmin utility. For example, to find out the number of current connections to the server, use: # mysqladmin -uadmin -p`cat /etc/psa/.psa.shadow` extended-status | grep Max_used_connections | Max_used_connections | 11 | The current connection limit can be found using: # mysqladmin -uadmin -p`cat /etc/psa/.psa.shadow ` variables | grep 'max.*connections' | max_connections | 100 | | max_user_connections | 0 In the above example, the maximum number of connections to the server (max_connections) is set to 100. The maximum number of connections per user (max_user_connections) is zero, which means unlimited. The default MySQL values can be redefined in /etc/my.cnf (/etc/mysql/my.cnf on Debian/Ubuntu). For example: [mysqld] set-variable=max_connections=150 set-variable=max_user_connections=20 Restart MySQL after my.cnf has been modified: /etc/init.d/mysqld restart Please note: if you set
