stale sys-devices-virtual-net-veth... devices in systemctl list-units after every docker run

[Bas Mesman]

Hello,

Every time I start a container (for example: docker run -ti ubuntu) I have 2 extra virtual ethernet devices according to systemd.

I started to notice this when one of my applications (which uses systemd service information over dbus) started to use to much memory. On the coreos host I noticed the following difference:

# systemctl list-units | grep  sys-devices-virtual-net-veth | wc

> 114474  572370 25527702

# ip addr show | grep veth | wc

> 21     273    2542

I have been trying to find out why but have not been successful yet.

Can anyone of you give me a hint where the problem might reside?

Tanks in advance
