Sorry, missed a number.  I think it is generating a warning because
your 15 minute average is above the level you wish to be warned at.
7.60 > 5.  Which you are already guessing.

My original thought was you should consider using the -r option which
may offer a more realistic number by which you can compare the user
experience to.    Check out /usr/local/nagios/libexec/check_load
--help for a detailed description of that option.  A load average of
15 is pretty insane by my experience.  Use the -r option and then go
from there.
