[Users] Radius accounting: what happens if radius server is down?

[Bogdan-Andrei Iancu]

Hi Cameron,

as far as I know, the radius client library does not provide any support 
for RADIUS server failover. OpenSER cannot do anything about this as the 
radius configuration is not available to it (it is directly loaded by 
the radius client library).

most probably you should try to come up with an HA configuration for 
your Radius server. Using a secondary logging backend is got, but see 
how this affects the load on your server.

regards,
bogdan
