I've had the same problem running bind9 (9.3.2, kernel 2.6.16), handling
~4000 queries per second at peak time. Never really figured out what is
the reason for it.

In my case I've upgraded to 9.4 and it solved the problem. If I remember
correctly, some memory issues were fixed in this release that could be
related to this problem.
