If you look to see which pid (crit show fdinfo-$pid.img) has an fd
info with the id 61 (your SOCK_PACKET socket), you can get the command
name from core.img (crit show core-$pid.img | grep comm). I'd be
curious to know what application this is, because it if is something
like systemd, it will come downstream to ubuntu and we'll need to fix
this soon :)
