  It looks like http://bugs.freeradius.org/show_bug.cgi?id=365

  The solution is to not re-initialize the modules on HUP.

  It works in *most* cases, because the code handling the HUP tries to
wait until all of the modules have stopped.  But if your back-end DB's
are slow, it doesn't have much choice but to proceed with handling the
HUP.

  Most people don't see it because the modules respond quickly.  I'd
say the first step to a work-around is to make sure none of the
modules you're using are blocking the server.
