Hi,I have a problem with one of the web servers I manage. It runs FreeBSD 6.2, Apache 2.2.8 and PHP 5.2.1. It runs a high-ish number of pre-fork processes (usually around 240).
What basically happens is that during our peak hours in the evening the site becomes very slow as does everything on the server. The top output shows nearly all httpd processes in the state "devfs" and the load is jumping up over 10 but the CPU is 70% idle. There's plenty of free memory, over 4GB, and lots of available disk space.
While it's in this state all disk access is painfully slow. I've checked all the drives and the RAID card status and everything appears to be fine. It also recovers itself after a few hours when the traffic dies down again.
I've spent a lot of today Googling but can't find any reference to this particular combination of symptoms. Does anyone have any ideas?
