Traffic/Packet RRD Graphs Missing ~9 Months of Data (i386)

[zod]

Greetings,

After completing the upgrade from version 1.2.3 to 2.0RC3 (i386 ARCH), it appears that the RRD graphs are missing just about 9 months of data (attached a screenshot).  Graphs for 8 hours, 1 day, 1 week and 1 month appear to working with no issues. Graphs for 3 months, 1 year and 4 years show a considerable gap with regards to traffic and packets (other graphs appear to be working with no issues).

Currently running the latest snapshot (i.e. built on Thu Aug 18 18:44:11 EDT 2011), but still see the gaps in RRD graphs.  It appears the issue first started when I upgraded from version 1.2.3 to 2.0RC3; unable to explain the gap in RRD graphs (no obvious signs of issues in system.log other than "apinger: Error while feeding rrdtool: Broken pipe" and "/usr/local/bin/rrdtool respawning too fast, waiting 300s.")…

Thoughts?
