From this I would be inclined to agree with Jay that this is some kind of
clocking/timing issue.
What does show controller for this int/pa show?

Subject: DS-3 Issue
Hi,
I just wanted to ask and see if anyone has experienced an "input error"
problem on a 7200 VXR with a (Serial DS-3) card.
Apparently, when I perform an extended packet "ping" with a 1500 datagram
size, I get intermittent dropped/failed icmp packets. Evidently, the local
DS-3 Card is experiencing input errors.
If I perform an extended ping with a datagram size of 50, all of the
requests reply 100%.
I am inclined to belive this might be a bad card or some issues with input
buffer memory. If any of you have any thoughts or have expeienced this
issue, any feedback is appreciated.
Thanks,
Richard Danu
