It appears that netfilter has gone berzerk and is taking your machine out.
Are you really sure that nothing is sitting there injecting new rules all
the time?
You mean a script calling 'iptables' to dynamically add rules? Nothing
like that at all. I dumped the current rules below.
Are you looking at the init_conntrack numbers? While they seem, in the
long run, to be getting larger, they're not increasing monotonically.
My ping latencies, and the CPU percentage consumed by ksoftirqd_CPU0
just go up and and up (albeit slowly).
