Re: mbuf cluster leak?
So this keeps happening and suddenly started without any configuration changes.
The only thing I changed (some two weeks before it happened first time) was
to bump IPFilter's mabucket and logsize.
I wrote a collectd plugin to monitor mclpl and now have nice Grafana graphs.
What happens is that mclpl stays constant and then suddenly starts to rise
approxymately linearily (at a rate of around 4k per hour), suddenly stops
rising and stays constant again.
This only happens on the gateway, not on several similar non-gw servers.
I tried ipfilter restart, but that doesn't help.
The weird thing is that vmstat -m shows ZERO mclpl Reclaims, but only on that
We now reboot the gateway every few days (as soon as mclpl has risen too much),
but that's pretty awkward for a server that used to run non-stop for years.
Any hints? Any way to log mclpl Requests? That's only 16k in two days, so
I guess wouldn't explode the logs if done.
