Pyun eventually fixed the issue by applying enough workarounds (it was likely a hardware bug in the NIC's chipset). However, it wasn't easy to debug unfortunately. :( Any ideas on where to start? from the 8.2 box (tbh.lerctr.org in the script): 8.2->PIX->Provider->Internet->Motorola SBG6580 (Time-Warner)->Trendnet TEG-160WS Gig switch->9.0 box (borg.lerctr.org). So, where do I start? I'd turn off IP / TCP / UDP checksum offloading on your NIC if it supports it, and see if you are getting network layer checksum errors. If the IP checksum is wrong, then it happened on the last hops between the NIC and memory or across the previous network hop. Good idea, but, it didn't show ANY errors on EITHER side (both are em nics).
