please let me check some points:

1. you used 9.5.1rc1 without any patch, right?
2. did you try 'rndc stop' at some point?  If so, did named stop
   cleanly or did it abort itself?
3. were you periodically reloading the server during the test?  I'm
   not sure if this is coincidence but the self-abort happened while
   reload operation in your both cases.
4. if the answer to question#2 is yes, is it possible to not reload
   the server and see if it changes anything?
5. is it possible to install (if not yet) libxml2 port to your system
   and enable statistics-channels?  then you can see more detailed
   information about how named uses memory.
