Both unbound and python accepts DNS requests, and it seems when 25% interrupt happens, only unbound is in *udp state, where it is 50%, both programs are in that state.
Try turning of hardware TSO/checksum offload if it's availble on your chipset? ifconfig <interface> -rxcsum -txcsum -tso -- I'm only using nfe chips right now, but w/ the TSO/CSUM on they lock up constantly under high load. We're pretty sure it's mostly the nfe driver, or the chips themselves, but have never ruled out some generic 8.x hardware offload issues.
