Is there a way how to indetify the reason why are some req. dropped? I.e. logging such requestest? LB  there is no lack of CPU or memory on the server, no drops in the UDP stack..
See the "dup" field.

  The NAS is sending duplicate Accounting-Request packets while the server is still processing the old one.  So, the new one is dropped.

  This is usually because the RADIUS server is slow to respond to a particular request.  i.e. transient load spikes, etc.
