Investigate the Apache server-status handler (assuming its still there in
2.2).  If you also enable the ExtendedStatus output from server-status,
it includes a table that shows the daemon PID, number of accesses for that
PID, current state, CPU usage, time to process the current request, 
client IP, virtual host and the first line of the HTTP request which
shows GET/POST and file.  Assuming thats still the same in Apache 2.2,
that should help you identify whats hammering your server. (I only have
Apache 2.0 to play around with here)
