[Radiusplugin-users] openvpn crashes, well sort of

[Symon Fenton]

I'm running openvpn with the Radiusplugin, on high usage servers and low 
usage servers. They are each touching the same freeradius server.

On the high utilized servers, one of the openvpn daemon's crashes, and 
will no longer take connections. It appears existing connections stay 
up. I have a cron job that detects when the crash has happened and 
restarts openvpn, but that's not a long term solution. I don't see 
anything in the logs that tell me something is up.

Server is Ubuntu 8.04. openvpn 2.1rc7, Radiusplugin 2.0c.
