This is the second report that I have seen on this. Do you have any 
dumps or have anything else in the event log? If so can you send this 
directly to me (and not via the newsgroup)? Which version of Windows XP 
service pack are you running? Do you have logs of what was happening 
when this was triggered? Was this after a AXFR transfer?

I have been working on fixing this.
