are dropped packets a sign of network problem?
in a xen environment , i see a lot op dropped packets via netstat -i

Is this a sign of network problems, or is it normal to see this kind of numbers? i'm not sure how to interprete the data. is this normal, bad, critical. What are your stats on this?

I guess i have a xen issue of some sort, but not sure what yet

Code:
[root@redhat06 xen]# netstat -i

Unless you have routers that detect denial of service attacks and drop packets deliberately, then you have some sort of problem on the vi series devices. Sorry I don't know xen, I'm guessing they are virtual. I don't believe dropped packets of the magnitude you see are an expected behavior. Anywhere. Somebody who knows your Os will have to comment to give a definite answer.
