Named Dying on True64

[Gerard Kaempfe]

Hello all,

I'm running bind 9.1.0 on True64 4.0E and every once in a while
(2-3 hours) bind will just die. I end up with this error in the log and
nothing else,

--: zone.c:5555: REQUIRE(iop != 0L && *iop == 0L) failed
--: exiting (due to assertion failure)

I've basically come to rely on Nanny to keep it up. 
Does anyone have any ideas or seen this before. 

Thanks
