Sleeping Processes Timeout?
Hello, Today, I started experiencing some issues on our website with max connections exceeded errors. In looking into this, I found that we had too many sleeping processes. I was not even able to login to the mysql server from a command line. Is there a way to set a timeout for sleeping processes? This is a small example of what I am seeing when I run a 'show processlist' query: +--+--+---+---+-+--+---+ --+ | Id | User | Host | db| Command | Time | State | Info | +--+--+---+---+-+--+---+ --+ | 584 | root | localhost | blogs | Sleep | 915 | | NULL | | 595 | root | localhost | blogs | Sleep | 900 | | NULL | +--+--+---+---+-+--+---+ --+ --- Thank You Jason Williard -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

The best thing to do, if that's the case, would be replace all the mysql_pconnect calls in your application with mysql_connect (or what ever the language-specific function name is). You could also set the wait_timeout value in your my.cnf to something shorter, but this would affect all your applications and does not address the source of your problem.

Re: Sleeping Processes Timeout?
I had a similar problem while connecting to mysql 4.0.21 throuhg MyODBC 3.51.11. If so you must upgrade mysql to 4.1 or downgrade MyOdbc to 3.51.06 Jason Williard wrote: Hello, Today, I started experiencing some issues on our website with max connections exceeded errors.
