So here's an interesting problem:
On NetBSD 8, 9, current, with both ipfilter and with npf, with different
kinds of ethernet interfaces (re*, wm*), run pkgsrc/net/darkstat. Pass a
lot of traffic (like a week's worth of Internet traffic). Stop darkstat.
Machine locks.
I had a go at reproducing this on NetBSD 9.99.79 with no luck. I was
just pumping several TB of data into nc running on the host, so no IP
forwarding or anything.
I do recall seeing a message about UDP buffer problems from the DNS
lookup child and I've had named running in small systems fail with
similar sounding error messages.
Maybe the problem is related to the number of DNS lookups the child
process is doing rather than the number of TB the parent process is
counting?
