The sorts of problems you describe are unfortunately quite common when
using the radius protocol.
In general, missing and/or duplicate accounting records are due to
transmission problems or saturated links resulting in dropped packets
and retransmissions. Less frequently the problems are due to bugs in
There is no easy fix either - it is usually the case that a packet
sniffer and a lot of patience are required to track down what is
happening. I suggest you start by checking a trace 4 debug from
Radiator and comparing it to sniffer traces and possibly NAS debug
information. The first thing to do is to find out if the problems are
due to dropped packets and if so, to fix the bandwidth issues that are
causing packets to be dropped.
There may also be problems due to slow database accesses, and again a
trace 4 debug will show what is going on. I highly recommend setting up
a Log clause with the LogMicroseconds parameter turned on (requires
Time-HiRes from CPAN) which will show you timestamps with microsecond
Finally, there may also be problems in the Radiator configuration file,
but to say any more we will need to see a copy of it together with a
trace 4 debug showing what is happening.

NB: have you included a copy of your configuration file (no secrets),
together with a trace 4 debug showing what is happening?
