  You can turn on SQL tracing to see the SQL statements.  Or, (it's
easier in 2.1.4), you can turn on debugging *only* for accounting
packets, with Acct-Status-Type Stop or Accounting-Off.

  The new "radmin" tool is very useful for tracking down these kinds of
issues.

  Only if you're using Simultaneous-Use.
