Re: [Openvpn-users] Assertion failed at multi.h:411 -> now 409

[Eike L. <e.l...@ic...>]

Hi, today we got the same error, after a "kill client" via the management interface.

Nov 21 15:43:08 myserver ovpn[1945]: MANAGEMENT: CMD 'kill clientXXXX'
Nov 21 15:43:08 myserver ovpn[1945]: clientXXXX/1.2.3.4:3271 SIGTERM[soft,] 
received, client-instance exiting
Nov 21 15:43:08 myserver ovpn[1945]: PLUGIN_CALL: POST 
/usr/lib/openvpn/radiusplugin.so/PLUGIN_CLIENT_DISCONNECT status=0
Nov 21 15:43:08 myserver ovpn[1945]: MANAGEMENT: Client disconnected
Nov 21 15:43:08 myserver ovpn[1945]: Assertion failed at multi.h:409

Nov 21 15:43:08 myserver ovpn[1945]: /sbin/ifconfig tun0 0.0.0.0

Debian wheezy:
3.2.0-4-amd64 #1 SMP Debian 3.2.60-1+deb7u3

openvpn:
Architecture: amd64
Version: 2.2.1-8+deb7u2

Any Ideas or need more information?

Regards, Eike
