Re: [Radiusplugin-users] OpenVPN Server Stalls on Radius Server Failure

[Ralf Lübben]

I have just tested the plugin (2.0c) if the radius server is not available or 
switched off during users are connected and with random connects and 
disconnects. I could not reprocuce the error.

It would be helpfull if someone can provide some log files after the server has 
crashed.
