Hi,
Are there any "magic" counters which (on intel) wrap at ~40-50 days uptime? We've got a couple of processes gone nuts (even after they are restarted). When I say "go nuts", I mean "chewing a lot of CPU".
strace shows they are repeatedly doing the following set of syscalls (see end of mail).
Suspiciously, tcpdump also chews CPU and that of course will also be calling gettimeofday() heavily.
Cheers Chris
