Your NAS keeps sending the same packet over and over again every 2 seconds until it gets a response (or gives up completely). Freeradius can't reply unless the db responds in time, so when it receives the same packet again it complains and logs an error message. If 2 seconds is not enough for your db you might try to increase the retry interval on the NAS (but this way you're rather masking the problem and not fixing it).
Thanks for the explanation. Is is possible to know if these errors are for authentication requests or accounting requests? Does FreeRadius ignore one of the requests and answer the other one?
