Hello -
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 NAS software.
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 resolution.
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.
regards
Hugh

Dear All,
I am From BTTB ( Bangladesh Telegraph and telephone Board). From June 1st we
are using mysql for authentication and online billing issues. Previously we
used flat file authentication from /etc/shadow file and used to make bill at
the end of month from the log data. Only 'timeused' from stop data was our
concern for billing. So duplicacy of start data or missing of stop data were
not at all a issue to us. But now it is found that we are getting two start
data/record for same user with same session ID, user and time. Also some time
no stop data is received against some start data. We are using one
Maxsession. But though no stop data arrives for any session of a user, he/she
can log in again with out problem.
Please help me to get rid from all these problem.

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