How reproducible:
Didn't try


Additional info:

Currently running kernel-2.4.9-e.30.  Similar crash occured about a 
week ago  - named crashed, but after restarting, I got a kernel panic 
(kernel-2.4.9-e.24). Today's named crash did not produce a kernel 
panic. 

The last time it happened the log showed only this:
named[20404]: exiting (due to early fatal error)
