[RADIATOR] Unknown reply from localhost

[Arthur Konovalov]

I have a set of Radiator with frontend and backends on the same server.
Sometimes I see warnings in the logfile like that:

Mon Aug 23 21:51:20 2010: WARNING: Unknown reply received in AuthRADIUS 
for request 138 from 127.0.0.1:1650

What reasons it can be for this? Overload? Is it possible to avoid it or 
trace reason?
I have quite big traffic and if enable trace level 4 huge file will be 
generated.

My simplified config.
Frontend:
