Would adjusting timeout values address this problem.
The main causes of sleeping threads are - applications that call mysql_pconnect - apps do not close their mysql connections once they are done with their tasks. - apps that open a connection, run a query, do some magic or go to sleep and then run some queries again. > > I was thinking of using / setting these values. > [mysqld] > set-variable = connect_timeout=20 > set-variable = wait_timeout=20 > set-variable = interactive_timeout=20 > set-variable = net_write_timeout=20 This will be OK if you have only apps that do point [1] and [2] of the above. If you have apps that do [3], they will throw an error when they see that the mysql server has closed their connection. -- Raj Shekhar - If there's anything more important than my ego around, I want it caught and shot now. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/mysql?unsub=arch...@jab.org
