[RADIATOR] Unknown reply from localhost

[Hugh Irvine]

Hello Arthur -

The usual cause for this is your Radiator server has timed out and sent a retry before the first reply has come back.

The first reply then comes back which Radiator processes normally, then the second reply comes back but Radiator has already dealt with the request with the first reply.

My guess would be that the SQL database inserts for the RADIUS accounting requests are taking too much time, which is causing the timeouts.

regards

Hugh

NB: 

Have you read the reference manual ("doc/ref.html")?
Have you searched the mailing list archive (www.open.com.au/archives/radiator)?
Have you had a quick look on Google (www.google.com)?
Have you included a copy of your configuration file (no secrets), 
together with a trace 4 debug showing what is happening?
