Graphs stopped updating.

My graphs are no longer updating.
Nagios is creating a the service-perfdata and the rrd files are getting updated, but the graphs are not.

I set up Drraw and configured it to make graphs from those RRD's and it has the same behavior. If I open service-perfdata it has valid data. I suspect ODS is updating the rrd's incorrectly.

Are there any known issues with this? Any places I should look at?

I moved all my RRD files and the ODs made new ones and graphing is now working again.

Any ideas?

ok, it happened again. So when the rrd files get to about 5mb the graphing stops.
The time stamps on the rrd's does still change though.
