  You have a version of Perl which is gradually consuming memory. :(

  Perl has a garbage collector, but it is notoriously bad.  Your Perl
script is using lots of memory, and leaking.  Since the Perl interpretor
is running inside of FreeRADIUS, it looks like FreeRADIUS may be
leaking.  It's not.

  Fix the Perl script so that it doesn't leak memory.  Use fewer
variables, don't automatically create new variables, ensure that you
delete every "complex" object you can.

  I haven't done Perl in a while, so that's about all the advice I can
offer.
