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

[Dustin Wilhoit]

I will get some detailed logs of the failure but it may be a week or so before 
I'll be able to get the time to lab it all up.  My previous logs show almost 
nothing on the default logging level and I can't really play around with them 
since they are in production use now.

I am not sure how long it takes after the radius failure for the OpenVPN 
service to seize up but I think it's at least a few minutes if not more.  
Perhaps it also needs clients trying to connect to push it over the edge?  
Again, I'll try to get you more details as soon as I can.

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.
