4.8-RELEASE-p13 named dies with signal 6

[laurent at perilith.com]

Hi,

For the past two weeks I've been having issues with named (8.3.4-REL)
unexepectedly dying. The logs always show the same thing, a number of
denied updates from various hosts and then following entries:

Nov 14 10:22:26 ns1 named[58447]: d_rcnt-- == 0
Nov 14 10:22:26 ns1 named[58447]: d_rcnt-- == 0
Nov 14 10:22:36 ns1 /kernel: pid 58447 (named), uid 0: exited on signal
6 (core dumped)

Here the gdb output:

gdb named named.core 
...
Core was generated by `named'.
Program terminated with signal 6, Abort trap.

#0  0x2811eba8 in kill () from /usr/lib/libc.so.4

and the backtrace:

Any ideas?
