mysqld shows high cpu usage over extended time, restart = normal
Occasionally in checking one of the servers, I noticed that mysql shows 85% + of cpu usage essentially leaving the server at 0% idle. After monitoring it for a few hours, the status did not change. After a stop and start of mysql, things progessed normally. Checking back a few days later I noticed it was once again sitting up there at 95% (or thereabouts) and doing nothing of value from what i could tell. Have restarted MySQL during peak usage times for that server and its database, and it has showed normal loads and CPU usage (approx 20% CPU with .1 to .3 load). Is there a known issue (running on FreeBSD 4.8, MySQL 3.23.55 MyISAM)? Is there something I should check when next I notice the high CPU usage?

hi, load). Is there a known issue (running on FreeBSD 4.8, MySQL 3.23.55 MyISAM)? its been a known issue for quite a long time use linuxthreaded version and it should work fine. although much of work has been done on threads implementation, there are still such problems with mysql. it happens even on freebsd 5.0 regards, terry -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

I used to see the same kind of behavior a while back with a MySQL installation I did for a client. It turned out that what was happening was a poorly designed client/server app was touching off this really huge query (lots of rows and lots of columns across multiple tables) and then disconnecting before the result could be returned. They fixed their app and the problem went away. Drove me nuts troubleshooting it. Anyway. Make sure you don't have something similar going on. -- Peter L.
