If you're not doing traffic shaping, it's possible that you tried to
exceed the port speed of that interface. I think that output queue
drops will show up in the PVC info like you've shown. Do a 'sh int' on
that physical int, and see if there's a similar number on the 'output
queue drops' section.

Subject: Dropped packets in pvc

Pulled this from one of the networks we monitor here:

DLCI = xxx, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE =
Serial0/0.2

   input pkts 20275664 output pkts 19938492 in bytes
1807487268
   out bytes 2019670889 dropped pkts 26 in FECN pkts

   pvc create time 41w3d, last time pvc status changed 01:15:43

My question is, listed above is dropped pkts 26.

Is there any other information that could be obtained as to the how/why
these packets were dropped?

It wasn't due to DE, as also listed above, there were no discard
eligables.

On another note, anyone else hear about the "incident" yesterday
afternoon with Accuring, et. all. in Newark.
Its made most of the night go by quickly tonite :)
