NetWare 6.5 SP8
named.nlm 6.07.05

Two servers on the lan running named.nlm, user's are configured to use both for failover. If I try to resolve "" or "" it causes both servers to die with:

debug 1:  createfetch: A
critical: exiting (due to assertion failure)
info: shutting down
What's an "assertion failure"?
How to fix it? (sounds like a bug for Novell)
My short-term is to create a local zone for to prevent external resolution altogether. Anyone have other ideas?
