Some additional information on the settings:
I'm using CL.ONE for both reading and writing; and replicate_on_write is true on the Counters CF.
I think the problem occurs after a restart when the commitlogs are read.
I'm using the the 0.8.0-rc1, with RF=2 and 4 nodes.
Strangely counters are corrupted. Say, the actual value should be : 51664 and the value that cassandra sometimes outputs is: either 51664 or 18651001.
And I have no idea on how to diagnose the problem or reproduce it.
Can you help me in fixing this issue?
