Same problem on my servers, after a regular update this morning.
$ lsb_release -rd Description: Ubuntu 12.04.3 LTS Release: 12.04
In my case, the errors logged in /var/log/upstart/procps.log are: error: "Invalid argument" setting key "net.ipv4.conf.default.rp_filter" error: "Invalid argument" setting key "net.ipv4.conf.all.rp_filter"
I need to turn off RP filtering. However, e.g. "sudo sysctl net.ipv4.conf.default.rp_filter=0" works fine.
