[Nagiosplug-help] check_dns problem

Does anyone know why I might be getting "DNS WARNING - nslookup returned 
error status" back from check_dns? It doesn't always happen, and it 
seems to happen less after upgrading to nagios 2.0b5 and nagios-plugins 
to 1.4.2.

I've tried check_dns from the command line on the nagios box, and it 
does occasionally return the same error, but by using host or nslookup 
directly (using watch, for ease of use!) it never comes back with an 
error, so I'm a bit stumped as to why this might be happening. In my 
previous job we were using nagios 1 which also used check_dns, but I 
didn't experience this issue back then.

Is anyone able to shed any light on what might be causing this issue? 
Googling and looking through the bug reports and archives didn't find 
anything relevant...

Kind Regards,

Hugh Jones
