#1040 - Too Many Connections Godaddy
programmers, just like you, helping each other. Join them; it only takes a minute: Sign up MySQL Error “Too many connections” up vote 17 down vote favorite 7 I am using MySQL 5.0 for a site that http://dba.stackexchange.com/questions/20479/how-to-resolve-too-many-connections-and-fatal-error-in-mysql-running-on-vps is hosted by GoDaddy (linux). I was doing some testing on my web app, and suddenly I noticed that the pages were refreshing really slowly. Finally, after a long wait, I got to a page that said something along the lines of "MySQL Error, Too many connections...", and it pointed to my config.php file which connects to the database. It has just been me connecting to the database, no other users. On each http://stackoverflow.com/questions/1202322/mysql-error-too-many-connections of my pages, I include the config.php file at the top, and close the mysql connection at the end of the page. There may be several queries in between. I fear that I am not closing mysql connections enough (mysql_close()). However, when I try to close them after running a query, I receive connection errors on the page. My pages are PHP and HTML. When I try to close a query, it seems that the next one won't connect. Would I have to include config.php again after the close in order to connect? This error scared me because in 2 weeks, about 84 people start using this web application. Thanks. EDIT: Here is some pseudo-code of my page: require_once('../scripts/config.php'); some html.. .. .. .. .. some more html.. .. .. I figured that this way, each time the page opens, the connection opens, and then the connection closes when the page is done loading. Then, the connection opens again when someone clicks a button on the page, and so on... EDIT: Okay, so I just got off the phone with GoDaddy. Apparently, with my Economy Package, I'm limited to 50 connection

When I try to login to the phpmyadmin, it denied access too many and shown "too many connections" and none of the application which uses database is working now :( . I google and increased the max_connection to 250. Still I cant get into mysql server nor myapplications are working. I haven't used mysql_close(); whenever I make a db connection. Is that the cause of this problem? What is the solution? php mysql phpmyadmin share|improve this question edited Feb 6 '14 at 15:22 Pablo 2,83111733 asked Feb 4 '14 at 16:30 Piya too many connections 3991824 you have shell access to mysql? if so login to it and run show processlist and you can kill the ones you dont need from there –ManZzup Feb 4 '14 at 16:32 but there s only 1 process in it –Piya Feb 4 '14 at 16:41 your code might be making too many connections to the db, ex: if a link is already existing to mysql you should use that than making a new link or too many users connecting at once, PS: check whether ur connections are persistent or not as well –ManZzup Feb 4 '14 at 16:46 If I remember right too many connections is not only thrown when to many parallel connections are active, but also when the maximum number of connections per user or per hour is reached. –t.niese Feb 4 '14 at 16:51 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote Kill all processes created by your web app through task manager(if youre Win user) or command line(for Linux).Then you should be able to get to mysql server.

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 ex
