  Accounting packets may be re-transmitted by the NAS.  They may be
received multiple times by the server, and recorded multiple times.

  The default configuration *should* catch most of these cases, and
record only one set of information for a session.  But some NAS
equipment tries hard to send broken accounting requests to the server.

  Look at the "detail" logs to see which packets get recorded multiple
times.
