I doubt that it has anything to do with the crashes.

It's possible, I suppose. Is your box a slave for any zones, and is it likely
that the master(s) for any of those slave zones are buggy DNS implementations
that would send a TSIG signed query as part of an AXFR response?

If you *really* want to get to the root cause of the crashes, you may need to
talk to bind-bugs and, if requested, send the core file off to them (assuming you
have one). Or, you could just upgrade and see if the crashes go away and, if so,
never really know why. Such is the life of a system administrator...
