[Openswan Users] waiting for mast0 to become free

[Peter]

Hi All!

CentOS 6.3
kernel 2.6.32-279.9.1.el6.local.x86_64 with SAref
openswan-2.6.38
xl2tpd 1.3.1-5.el6

I can't restart correctly openswan…
Infinite output on the screen:
unregister_netdevice: waiting for mast0 to become free. Usage count=20.
...

We have to turn off the server on the button. :(
