I have a server that is experiencing high load values for some unknown reason. It is an AMD64 dual proc box (3000+, I think. Maybe faster.) with 4gigs of ram. The drive(s) are two SATA drives that are software mirrored. I am running the 64 bit version of Fedora Core 2. Not certain which kernel version. (It is maybe a month old.) I am not hitting swap at all. MySQL rarely even shows up on "top". The CPU percentage used is almost non-existent. The load when MySQL is being queried is 0.9 or higher. (Usually 1.0 on average.) The queries should not be hammering the box that much. What is actually causing the scheduler to choke is unknown at this point. Any ideas how I can find the cause of the problem? A previous semi-related message suggested adding "elevator=deadline" to the kernel options. I have not tried that yet. (I will tonight, but since this is a live machine and they swiped my test machine, I have to do this carefully.) Any ideas?
