The questions are quick...
Looking at this I'd guess uptime has been a few hours, or else several
months, because the counters reset when they overflow or when you
restart the interface.
Error rate is around 0.027%, so it might not be worth fixing. Your call.
Overruns are typically caused by the next packet arriving before the
interrupt service routine is done emptying the buffers. That would
indicate a fast sender at the other end, many senders talking at once,
or a slow driver or malfunctioning card. Check for duplex mismatch
too. That's about all I can infer with this information (not that I
know all that much more about it).
