My biggest challenge is trying to duplicate the a loaded system which seems to be an important component of the failure you're seeing. Simply blasting traffic with netperf hasn't been much of a challenge as it runs over the weekend at line rate without a hiccup. If anyone has an idea on how to load the system (which means regular failures by the driver to allocate mbufs) I'd definitely appreciate hearing it so that I can duplicate Tom's environment. It's certainly important to me that the driver perform well and I won't stop looking at the problem if you do decide to jump ship. Dave
