I have also seen this issue, but have always put it down to the way that
we manage our nagios deployments with cfengine.  I will try to deploy
this change and monitor for the problem to see if it persists.

On a side note if you want to use broker modules with nagios from port
you need to change the following in the port Makefile in order to make
them load properly:

From:
USE_AUTOTOOLS=  autoconf:259
To:
SE_AUTOTOOLS=  autoconf:259 libltdl:15


I sent an email to the maintainer but got no response and my email did
not seem to have affected the last commit to upgrade to 2.10.
