Just an update on this issue and to letting you know your report is not ignored. I have been working with Sherin George offline and we have Been pulling information off Sherin's server box. The box becomes unresponsive after about 4 days. The routing table is fine is properly accessed. The ARP table is properly accessed. Through packet capture, the packets seem to flow into the driver but appear to be stuck somewhere after the driver handoff. The device stats do not show any link related errors. The device is "em". Initially I was suspecting the flow-table module, but after disabling the flow-table lookup and various experiments, the problem points to L2 (after ether_output). According to Sherin, the box will regain network connectivity after some time. At this point I am thinking about creating a special debug build and run it in Sherin's environment. -- Qing > -----Original Message----- > From: owner-freebsd-net@freebsd.org [mailto:owner-freebsd- > net@freebsd.org] On Behalf Of Kenneth Hilmersson > Sent: Friday, January 29, 2010 1:46 PM > To: freebsd-net@freebsd.org > Subject: Strange network issue in freebsd 8 > > > The servers loses network connection once in a few days.
