I?m running a web server with dual Xenon 2.8 CPUs, 4 Gigs of RAM, Red Hat 8.0, and Apache 1.3.x. Since installing the server, for the last 9 months, the server?s CPU has been 99% idle, and has not used more than 2 Gigs of physical memory. That?s with pushing out over 40 Gigs of content per day with 1.2 million page views.

Over the last few days I?ve been getting an out of memory error and the server grinds to a crawl. I changed the MaxClients settings on Apache from 1024 to 512 and that solved the memory problem. However, the CPU is now pegged at 99% user, 1% system, and 0% idle.

I?ve been struggling with this for about 3 days now. I talked to another webmaster running IIS and he says that his quad processor web server is also pegged. His problem started at about the same time as mine. Given that we?re on totally different platforms, I?m thinking that there is some type of DoS going on but all the log files look normal.

Is anyone experiencing this problem? Any ideas on what?s going on?

Thanks in advance for any assistance.
