Gotta problem
For some reason, many of my persistent connections aren't terminating. I end
up with up to 30 connections to MySQL that aren't being used. My guess is
that the user connection is slow and the script never finishes running or
something.
Is there a way to get all my connections to close, or is there a PHP script
that can close any unused connections???
Regarding persistent connections, this is how I believe it works:
In apache httpd.conf you have:
MinSpareServers 5
MaxSpareServers 10
The MaxSpareServers gives you the maximum of apache daemons running
simultaneously.
In php.ini, you have these statements:
mysql.max_persistent= -1
-1 is default, change this to the number of maximum persistent connections
per apache daemon. This will give you the following formula:
total_persistent_connections = MaxSpareServers * mysql.max_persistent
The MySQL-configuration my.cnf:
set-variable= max_connections=255
set-variable= wait_timeout=3600
Make sure that total_persistent_connections is less than max_connections,
to give you some overhad for non persistent connections and other mysql
sessions. The wait_timeout variable is simply the maximum idle time for a
connection to exist. Lower it if you have still have problems with the php
persistent connections.
This should really be in the FAQ.
