Public bug reported:
Detected when I failed to start a vpn client session.
journalctl shows line like:
sept. 13 10:37:29 xxx NetworkManager[1092]: <warn> [1505291849.7302]

not launch the VPN service. error: Trop de fichiers ouverts.
Indeed, /proc/$PID/fd is full of socket file descriptors. (with PID the
pid of NetworkManager)
"strace -e socket -p $PID -f" shows that a netlink socket is opened
every 3s and never closed.
