Well, thanks to all, the problem appears to be resolved.  As I mentioned in a 
earlier post, I moved my secondary DNS to twisted4life and at that point the 
problem appeared to disappear.  Based on Rod's explanation, that would be 
because ns1.twisted4life.com is registered in the whois database, so, even 
though ns1.walma.org is not, having one registered was sufficient to resolve 
the problem.  I will contact my registrar to get ns1.walma.org registered as 

I must admit, and I am no DNS expert, that nothing I'd read to date on DNS 
suggested that this could/would be an issue.  My understanding of DNS was 
that, when trying to resolve a host name, your dns server would query the 
authoritative name servers for the top level domain, get the names and IP 
addresses of the authoritative name servers for the domain, then turn to 
those name servers to completely resolve the host name in question.  No whois 
in the process.

I can certainly understand how whois could be used in fighting spam.

So, can someone help me with my education?  Where in that process does whois 
occur?  Why did DNS work for 99% of the world and only fail for 1%?  Either a 
direct explanation, or a pointer to the literature, would be appreciated.

Thanks again to all for assistance in resolving my problem.
