Bug #13589 Updated: Persistent connections stay open and accumulate

ID: 13589 Updated by: zak Reported By: mtremblay@sitebrand.com Status: Open Bug Type: MySQL related Operating System: RedHat 7.1 PHP Version: 4.0.6 Old Assigned To: Assigned To: zak New Comment: Assigning to myself Previous Comments: ------------------------------------------------------------------------ [2001-11-20 12:55:15] derick@php.net However, this is something else. This need to be investigated first. ------------------------------------------------------------------------ [2001-11-20 12:31:00] sander@php.net This is what Derick said about this (in #14149): This is not a bug, the MySQL extension will open a new connection if the _current apache child_ has no open connection to MySQL. With this in mind, it's very normal to see that apache has multiple connections open to MySQL. ------------------------------------------------------------------------ [2001-10-07 17:33:26] mtremblay@sitebrand.com While trying to use persistent connections for performance on an ad server, connections to the MySQL server stay open and accumulate over time until it hits the max_connections setting is hit. Once this happens, MySQL refuses to allow connections. After looking at the MySQL process list, it seams that connections are not always recycled. In theory, idle established connections' Commands should be "Sleep" but curiously, it looks like connections not being recycled have "Query" command and a state of "NULL". Presently using MySQL 3.23.36. ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=13589&edit=1
