netgraph - write failed: device not configured

[Christoph Kukulies]

I have a problem with running a VPN client against a Cisco VPN server.
The client is 5.0-current. I'm running mpd and the recent bad malloc 
seems to be gone. But the effect, that connections die with 
'write failed: device not configured'.

It happens inmidst a VPN session (which is established via ng0 as a
kind of ppp connection (/usr/ports/net/mpd/work/mpd-3.13)

It doesn't say which device is not configured or which device failed on
write but I suspect it is ng0.

ifconfig still shows the point to point addresses but trying
to reconnect (ping the peer side) just gives: no buffer space available.

Memory leak in netgraph?
