Is there database access during this? High load is not indicative of the
CPU working hard. High load, in this case, is due to the CPU not getting
answers back fast enough, and processes queueing up (eventually shutting
down apache). It will consume all available threads (connections), then
start killing the box.

-What external dependencies are there (if any)?
      - Databases?
      - External Calls?

-Do you have high timeouts on anything?

-Is it just very inefficient code?

At this point (in my experience), if you do not see a clear indication of
the issue in the apache logs, it's not apache.
