Assert Failure (BIND 9.4.1-P1, Freebsd 6.2, DNSSEC)

[Gushi]

Hello all:

I'm running the above versions of things, and am also doing DNSSEC
validation against the ISC DLV registry.

Named dies after a short time with the following:

Aug 18 03:38:26 <daemon.crit> prime named[72049]: validator.c:202:
INSIST(val->event == ((void *)0)) failed
Aug 18 03:38:26 <console.info> prime kernel: Aug 18 03:38:26
<daemon.crit> prime named[72049]: validator.c:202: INSIST(val->event
==
 ((void *)0)) failed
Aug 18 03:38:26 <daemon.crit> prime named[72049]: exiting (due to
assertion failure)
Aug 18 03:38:26 <console.info> prime kernel: Aug 18 03:38:26
<daemon.crit> prime named[72049]: exiting (due to assertion failure)
Aug 18 03:38:26 <kern.info> prime kernel: pid 72049 (named), uid 53:
exited on signal 6

Does anyone know what could be causing this?

Does anyone want me to get a coredump, or something similar?  (Or, ISC
staffers, if you want access to the system in question, please contact
me off-group).

Similar request has been posted to the dnssec-deployment list.
