I see a lot of them too but they don't seem to hurt.
Perhaps digging into particular failure cases could teach us

'netstat -W athn0' shows several counters related to input failures
and should tell you where these input failures are coming from.

The first looks like confused client devices. The second
looks like some ACKs we sent got lost for some reason.
Neither is a fatal problem.
