> From the cassandra user message board:
> "I just recently upgraded to latest in 0.5 branch, and I am running
> into a serious issue. I have a cluster with 4 nodes, rackunaware
> strategy, and using my own tokens distributed evenly over the hash
> space. I am writing/reading equally to them at an equal rate of about
> 230 reads/writes per second(and cfstats shows that). The first 3 nodes
> are seeds, the last one isn't. When I start all the nodes together at
> the same time, they all receive equal amounts of reads/writes (about
> 230).
> When I bring node 4 down and bring it back up again, node 4's load
> fluctuates between the 230 it used to get to sometimes no traffic at
> all. The other 3 still have the same amount of traffic. And no errors
> what so ever seen in logs. "
