I'm not quite sure how to check out all these things...
The server is doing backups. Naturally most of the traffic happens
during night hours.
But more fundementally, why are you even concerned with
2916/689587830
packet drops? On most scenarious, this is pretty normal behaviour.
I'm concerned because occasionally the backup application shuts its
TCP port on which it listens. It seems to happen after a considerable
amount of drops/errors have accumulated on the interface. The only way
out then is to recycle the app. I suspect that these errors might be
the indication of the problem that causes abnormal application
behavior.
i would be more curious why there are 2900 errors :)
I realize there might be a million different reasons for these errors.
How can I investigate them?
