In the other direction, I would recommend removing swap and
reducing RAM to 256MB. For a service like DHCPd, it's better to
fail and restart than to just try to eat all available memory.
Then set vm.overcommit_memory=2 in sysctl to enforce that rather
than OOMd.
That said, there is probably something else going on here. Logs
on a tmpfs, maybe?
