Reason for Ierrs in netstat


one of our servers has some network issues. Symptoms are: Bad ping (twice
as high as comparable machines on the same net), packet loss and increasing
number of Ierrs in "netstat -i".

Is there any chance I can find out the reason behind those Ierrs?

I rebooted the system a few hours ago, and there are some Ierrs again

tethys# netstat -i
