rrd gaps

[Brock Kuhse]

Odd.  The relevant portions of my working configuration are functionally
identical yours.  I have no HOOK statements in my nagios grapher
configuration, though I can post the full file on the off chance it may help
(if you feel like sifting through it).

It might be worth trying to run the process-service-perfdata command
directly to see what happens (probably while tailing the ngraph log, and
running the command as the nagios user).

Good luck.
