RRDs created, never updated

[Jeremy Cappilero]

I've been using BB/Hobbit with RRDtool for, I guess at least 5 years, maybe
more.  I've installed it successfully on maybe 10 servers.  Things certainly
got easier with Hobbit compared to BB!

I've just installed Hobbit on a Centos 5.2 box and for the life of me I
can't work out why my RRDs aren't getting updated (they are always created
during first run, but never updated).  I've grepped every log, history file,
etc I can find and can find no hints.  Can someone suggest where to look for
errors or problems to do with *updating* the RRDs?

Everything is stock, I haven't touched the bb-hosts file, indeed anything
really...

Extra info... The RRDs are created when hobbit is first run
