Flowd doesn't support NetFlow v.9 "options flowsets". When I wrote the 
Netflow v.9 code, I didn't have access to anything that generated them
and I recall finding the documentation on them somewhat unclear.

If these are all you are receiving, then you won't see anything logged.
Otherwise, could you send me your flowd.conf?
