After update to 0.9.12 latest graph points are always missing.

In my environment I have two graphite servers that both have a single carbon-relay and carbon-cache running. Carbon-Relay is setup to push ALL metrics to both boxes so I have a mirror of the same metrics in both places.

Both boxes were running graphite 0.9.10. I just updated one of the two boxes to 0.9.12 and noticed that on the updated box I no longer am seeing the most recent metrics in graphs. If I keep refreshing I see static data, then after roughly 5 mins or so the graph will update to recent (carbon-cache flush to disk?). Then no updates at all for another 5 mins or so. When I bring up a graph for the exact same data point on the 0.9.10 box I always get realtime data points. I'm using a metric that's being updated every 10 seconds for this test.

So it looks like my graph query is only pulling data off of disk, and not from carbon-cache. The graphite configs up the updated box have not really changed. So I'm kind of stumped.
