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

[Ralf Lübben]

Hi,

if the problem occurs if all RADIUS servers are down it is probably related to 
the plugin, but without a log file it is only guessing.

Please use a OpenVPN verbosity level equal to 5, than you will get additional 
output from the plugin in the log files. Maybe this will give a hint.

You can also try the beta version of the plugin, a lot of issues where fixed in 
the last days.
