I'm curious if anyone knows the cause/solution of this one. I've never seen it personally, but I've seen at least half a dozen reports in the bug database and newsgroups.
Basically, people report that processes get "stuck" in keepalive and eventually fill up all the process slots, bringing the server to a halt: http://bugs.apache.org/index.cgi/full/8725 http://bugs.apache.org/index.cgi/full/8261 http://bugs.apache.org/index.cgi/full/8045 Some people report success with a signal change: http://bugs.apache.org/index.cgi/full/3906 Joshua.
