TemptorSent (Chris Giorgi ) made some changes to apache mpm prefork
config
I'm including the change here, since it contains no big secrets
{{{
+
+# Set MaxClients based on memory consumption per worker, which appears to
be
+# approximately 64MB unshared per instance. At max loading, this 100
workers
+# should consume 6.4GB or less, leaving sufficient memory for other
services
+# to avoid hitting swap. This may be decreased if resource contention is
+# observed, or increased if resources allow and connection numbers are
high.

I applied the patch to trac.osgeo.org and did an apache reload.
Things seem to go more smoothly after and I didn't see as much cpu spiking
in top or ps aux output. Might be wishful thinking on my part or because
of the apache reload.
Anyrate will keep this ticket open. Chris has more changes he'd like to
put in place to help.
Discussion about all of these issues are on irc:
