I checked the accounting text log in /var/log/radius/radacct/nasip and I see no duplication in that file for the same record shown below, it only appears once (it is an Interim-Update). Any ideas as to what the problem might be and how to fix it?

  If you have the correct indexes on the tables, then it *cannot* insert two rows with the sam Acct-Unique-ID.
