The logs do not show anything that I don't understand or that I can relate to this problem, and none of the other options are possible as this is a production machine. On a duplicate machine that runs mysql replicated from the first, and doesn't have any load, stopping the mysqld caused the load to fall to almost 0. There were very few hardware interrupts after that (as evident from /proc/interrupts) but there isn't any load so I don't know. -- Oded ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
