net-snmp (from ports):

Sypnosis:

I said "nonsense" and I meant two things:
- snmpd thinks that the host is only receiving traffic, and not sending, that's not true.
- snmpd thinks that there's a HUGE amount of errors, that's not true either. One can suppose that this counter does correspond to some error counter in the netstat, but I don't see any that would fit.

Plus, I have an identical server with identical ix(4) interface, same net-snmp version (and same config) and it's output counters aren't zero (or almost close to zero). It's built with same port configuration/options, so I have no idea what triggers this weird behaviour.
