When asking about a non-standard plugin, it's very useful to also include where
you got that plugin. How it does what it does is very relevant to your question.

How does it determine this?

Much more likely is that the script is using something like '/bin/du' to
calculate the size of the directory and that it is sometimes taking longer than
you've told nagios to wait to do so. That doesn't really surprise me for a
directory of that size.

Look at your check_nrpe command definition. If it specifies a timeout value
(-to), increase it as needed. If it doesn't, add one. Also check the value of
service_check_timeout in nagios.cfg. It should be higher than the check_nrpe
timeout.
An even better solution is to make that directory it's own partition. Then you
can use check_disk, which will be nearly instantaneous, to determine the size
of the directory.
