Try and get a profile from when the CPU is not pegged, and when it is
pegged. That means finding a profiling tool for your platform that
can attach to a running process. For Itanium that would be one of
Caliper (Linux or HP-UX) or q-syscollect (Linux). I'm not sure what
they would be for other platforms, but would love to learn.
Looking at the data for c.ns.sr.sonic.net I see that the ifPackets
seems to increase over time as well, then drop to nearly nil - when
the CPU spikes? It also seems that there is a point where the forks
spike? Etc etc.
Is there any chance of something, well, nefarious happening here?
