Thank you for the tip, but this is not our problem. We are running SCSI
disks with over 40 MB/sec throughput. Any other ideas?

This is what I used to have. We invoked the scenario described in
http://linux.oreillynet.com/pub/a/linux/2000/06/29/hdparm.html
and since then things went back to normal without any other
tuning. Oh, one more thing: I changed pconnect to connect in php.
So it looks as like we had load problems at times due to poor hd
performance which gave trouble to mysql.
