I have found /proc/net/ip_conntrack to be a reliable indicator of the number
of connections through a system (at least, I've not had a problem of running
out of connections unless ip_conntrack = ip_conntrack_max, and I see the
number of connections go up and down very plausibly with the time of day),
and I have systems running for months without a reboot.
Please let us know if you find something in the code to explain what you are
seeing.
