apache hangs after some hours of running

Here is some info that would be helpful.  I realize that you have sent
some of this to particular individuals in the past, but I don't see it
in the PR.

At the time of the hang:

  how many child processes and what are they doing? (run pstack against
  each one to see what is going on; presumably most of the children will
  have the same backtrace, so no sense sending in duplicate backtraces)

  what is the parent doing?  run truss against it for a while (15 seconds)
  if it doesn't appear to be doing anything, run pstack against it to
  get a backtrace

  is it possible that all available children are handling connections?
  look at netstat output for ports served by Apache to see if there are
  enough hung connections to represent each available child

wild and crazy idea:

  try a different accept mutex mechanism (e.g., "AcceptMutex fcntl" in
  httpd.conf)
