what do netstat block check or framing errors mean

Our users been experiencing dropped [database] connections to one of our Alpha
servers (4.0g, no patches). We notice lots of errors (see below). We've tried
swapping the cable and to the other ethernet port (DS10 w/ dual onboard ports).
  Does this sound like a h/w problem? Maybe at the switch port?
