Right, there seems to be a bug with this default value then. Without any
fastpath directives, memory grows and grows.
Fastpath set to 1MB:
nsd starts at ~4MB, grows to about 6MB. Perfect.
Fastpath set to 5MB:
nsd starts at ~4MB, grows to 10MB. Just like it should.
This is both with the 4.0.1 I still have on my dev box, as well as with
4.0.8 I use for production.
Cheers,
Bas.
