odd permissions problem

It does create it when nagios starts, and the command {} entry is
correct.  The host{} and service {} entrys in the objects.cache are also
correct. Is there any other way  you can think of that Nagios could pass
one set of command arguments to the service check and another to the
host check? 

Thanks for your help,
Casey
