I'm thinking that maybe I'm running into a user limit (httpd) rather
than a process limit. I show only 60 or so open handles per httpd
process, with a system limit of 1024. Is there such a thing as a user
limit? I know there are limits on the number of user processes, but I'm
not sure about open file handles.
I may try to attack the problem short-term by having apache throttle
back to less httpd's when idle, and lowering MaxRequestPerChild to
have the children die earler.
