duplicate records

[Callis]

Hi all,

   I am trying to use freeradius(1.0.1-1 on FC3) to 
collect AAA records from a CISCOAS5300. I keep getting 
this error in my radius.log and my cisco also reports most 
of radius timeout. A ping test give <10ms on my network. 
Any suggestions would be of great help. Thank you.
