There's a 1024 character limit for exit text in the NRPE protocol.  
This used to be the limit for nagios itself until nagios-3. http://opsview-blog.opsera.com/dotorg/2008/08/enhancing-nrpe.html

They're being evaluated, just not passed in the 'for humans only' text  
part.

NRPE/nsclient++ may not be the tool for the job. I am not aware of any  
windows clients that extend the NRPE protocol beyond that 1024  
character limit or implement the opsview extension.
