Sup32, the port is on the sup32 itself, and the whole box is not really
doing that much - total throughput right now is at about 150 Mbit/s,
and there isn't anything with known-bursty characteristic either (and
all VLANs coming in on that port go out on another ethernet port with
no load on it).

The errors don't really correlate to "load" either - they just increase
slowly over time, by something like 20-150 errors per 5 minute interval.
