I will take a look next time the event happens while I'm in the office.
What you describe seems to be what happened when MaxClients was reached
last time. Lots of processes running, but none of them getting anything
I did notice some MySQL processes taking more time and processor usage
then normal last night so I decided to run an optimize on all of my
tables. The site definitely sped up and the site did not need a restart
last night. I'm not sure if they are connected or not, but perhaps John
and Jeff can run optimize on their tables and then see if the issue
continues to happen.
