Well that's kinda not our problem, but just a shitty network driver or distro stack. At least if the problem really is just the lost IP and not that the machine dies somehow. So as long as restarting the network connection fixes this bug this is a network driver/stack issue I think. If it's annoying we need to pull in the network guys (no idea who might be suitable).
