We have seen the behaviour described in first message on two of our nodes:
NSD 4.0.1 and 4.0.3 went completely unresponsive when sockstat showed
few thousand TCP connections. Both nodes operate under FreeBSD 10.0.

Recently I updated NSD to 4.1.9 and now am waiting if problem appear again.

Is there any problem Exterminatus cannot solve? I have not found one yet.
