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.=20 Through packet capture, the packets seem to flow into the driver but appear=20 to be stuck somewhere after the driver handoff. The device stats do not show=20 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=20 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 >=20 > > The servers loses network connection once in a few days.
