You should close them in application after using. Another variant is to setup wait_timeout server variable - the number of seconds the server waits for activity on a non-interactive connection before closing it. Not used connections will be closed automatically. share|improve this answer answered Nov 9 '12 at 10:20 Devart 76.1k12100120 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

Kindly help me to resolve this problem. mysql phpmyadmin php share|improve this question edited May 14 '15 at 15:05 mustaccio 4,80411326 asked Jul 6 '12 at 6:43 Shashank 1374414 @RolandoMySQLDBA: Please Enlighten on this problem to resolve –Shashan
David · October 12, 2012 MySQL too many connections. Of course this simply means there are too many connections to the MySQL database. This can happen on a very busy site or even on a site with few visitors that contains poor coding that doesn't drop connections. To fix it, you can go one of two ways. Through SSH using MySQL commands or by adding a directive to the global configuration file (/etc/my.cnf). ------------- For editing the configuration file, simply add the below directive to the configuration file. /etc/my.cnf max_connections=XXX Then restart MySQL services: [01:50:26] [root@localhost ~]# service mysql restart Shutting down MySQL....... [ OK ] Starting MySQL. [ OK ] ------------- To change it via command line, you will need to be root and log into MySQL and use the command "set global max_connections=XXX": [01:50:37] [root@localhost ~]# mysql Welcome to the MySQL monitor.

However, is there any danger is changing the value to a number as high as 5000 (per your example above)? What are the pros/cons involved? Reply David says: January 27, 2016 at 11:23 AM It depends on the traffic you're receiving. Around 1000 connections is the maximum before you want to start load balancing and clustering. Setting it too high will result in the server crashing after it runs out of memory. If you have some pages or parts of your website or application that are not closing connections, you should review the programming and reasoning behind why those connections are staying open. A site like WordPress, for example, will: - O
