Subject2.2.10 gone nuts?

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

oldselect(1, NULL, NULL, NULL, {0, 1}) = 0 (Timeout)
gettimeofday({934830292, 915696}, {0, 0}) = 0
gettimeofday({934830292, 915875}, {0, 0}) = 0
oldselect(1, [0], NULL, NULL, {0, 0}) = 1 (in [0], left {0, 0})
read(0, "", 256) = 0
gettimeofday({934830292, 917076}, {0, 0}) = 0
ioctl(8, FIONREAD, [0]) = 0
gettimeofday({934830292, 917940}, {0, 0}) = 0
