Does the problem go away if you modify your check to use check_dig
instead?

(nslookup is deprecated, although that probably isn't your problem
let's stop using it anyway)

BTW I am at the moment trying to write my first plugin which will
use Net::DNS perl module to get the SOA of an rbldnsd-hosted zone,
giving warning or critical based on how old the SOA timestamp is.

Has anyone else written that before (google does not help)?

If not, if anyone wants it when I've finished then drop me a mail..
