[users@httpd] Apache reaching MaxClients despite what appears to be moderate server load

[Jim Keller <ji...@centerfuse.net>]

One of my webservers has started acting up, and I'm not entirely sure 
what's going on. It seems to act as if it's under very high load, even 
occasionally reaching MaxClients and shutting down, despite the fact 
that it doesn't appear to be seeing *that* much traffic (at least it's no more than usual). I've been 
keeping an eye on /server-status, and at one point when I noticed it 
starting to spiral down again, there were a lot of requests listed in 
/server-status that had no host, no vhost, and no request. Those fields 
were just dots. I'm really not sure what this indicates, but was hoping 
someone could shed some light on the problem. I tried enabling 
MaxRequestsPerClient and lowering the KeepAliveTimeout, but the issue 
still seems to be present. This is Apache 1.3.34 on FreeBSD. It's been 
running for over a year without hiccup until this week.
