[-- Attachment #1 --] All those duplicate ACKs look like a problme to me... I would be inclined to capture from the other end or from a monitor port on the switch to make sure those are actually hitting the wire. The only explination I can think of is that the system sending the duplicate ACKs is assuming that it's lost a segment for some reason and is trying to trigger fast recovery early.
