I'm running the v0.7-beta1 in a 4 nodes cluster and just doing some simple testing. One of the nodes had been down (machine off, unclean shutdown) for an hour or so not sure how many writes were going on, when I bought it back up this message appears in the other 3 nodes...

I ran a repair on all the nodes and this was all that they each logged

Cluster seems fine. Should I create a Jira ?
thanks
