close all db connections "too many connections error"

Posted on 2009-05-06
Last Modified: 2013-12-13

a shared web server i use recently got an error "Too many connections" all my php code closes the recordset connection at the bottom of page so i thought it may be a database connection. We ended up increasing the connection limit to 500.

i added this to one test site where i know only 1 or 2 users is on the site

but we still have 13 connections , but all with Kill runs on them (whatever that means)

is their anything I can add to my website footers to make sure all the recordset and db connections close after page loads?

could it be another problem i dont see?

is their an another server based solution? (windows server)
<?php mysql_close($mine); ?>

Open in new window

 Hi jblayney ,
      It seems something related with your host firm.Even if you have 13 active connections it shouldnt create any issues as you mentioned above.Also using mysql_close() is not necessary if you are not using persistent connections as far as all connections will be closed at the end of script execution.
     To minimize the DB connections you should use singleton pattern , during your database connections, but this is not the exact solution you need.
     If i am not wrong you get the error not because of active connections made from an mysql account,  generally multiple connections from different mysql accounts cause this kind of issues.
    Do you get the error when you run phpmyadmin or some kind of other database management tools ?

yes, i fist noticed it using phpmyadmin

i also use dreamweaver to do my connections and basic coding. it closes all recordsets. eg.. it looks like is makes persistant conenctions.. (pconect)

$mine = mysql_pconnect($hostname_mine, $username_mine, $password_mine) or trigger_error(mysql_error(),E_USER_ERROR);

i actually found that thread before i posted here. it is easy to change to connect, you do that simply in your connection file.

i just guess im looking for  the bigger explanation. I have used dreamweaver for many years and many versions. they get many things correct and it seems silly that they would overlook something like this.

i am going to change all the sites i built on that server to mysql_connect and see what happens
