I had a similar problem when writing my pipe backend program, also in Perl.
I think the problem originated from copying some examples found on the net.
My pipe backend outputs SOA results as:
[ $qname, $qclass, 'SOA', 86400, -1, $soa_str ];
where $soa_str is a string (using *space* as separator) like:
"geo1.opera.com. hostmaster.opera.com. 2011111601 28800 3600 604800
So, the pipe backend replies to a SOA query with:
DATA \t testdomain.com \t IN \t SOA \t 86400 \t -1 \t $soa_str
The last element, $soa_str, the actual SOA record, should be *space*
_not_ tab delimited. That was my error, at least.
