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?
Process shall set you free from the need for rational thought.
these opinions are mine, all mine; HP might not want them anyway... :)
feel free to post, OR email to raj in cup.hp.com but NOT BOTH...
