I'm not quite sure how to check out all these things... The server is doing backups.

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? _______________________________________________ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
