Version-Release number of selected component (if applicable):
bind-9.8.2-0.10.rc1.el6.x86_64

How reproducible:
Unfortunately unknown, just happened after running for 4 days and hitting
a lot of DNS queries by clients.

Actual results:
Crashing BIND - causing lots of trouble.

Expected results:
BIND should not crash anymore.

Additional info:
BIND configuration as follows (without comments and IP replaced):
