Was there a specific reason why you are using RRDtool 1.3.3?  I'd
imagine you have to build this manually on CentOS 3.  Any chance you
can downgrade to an older version (say 1.2.x) and see if your problem
goes away (make sure you backup your rrd files though...).

With only three nodes, I doubt you are reaching any sort of
scalability issues addressed in the new version of RRDtool 1.3.x.
Also I wonder how well it works under 2.4 kernel...  did you have much
trouble building RRDtool 1.3.3 (and all the dependencies) on CentOS 3?

I have briefly tested Ganglia 3.1.x with RRDtool 1.3.x under CenOS 4.x
and didn't have the issue you mentioned.
