I'm using CL.ONE fo= r 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 a= re read.

Hello,

I'm using the the 0.8.0-rc1, with RF=3D2 and 4 nodes.
Strangely counters are corrupted. Say, the actual value should be : 51= 664 and the value that cassandra sometimes outputs is: either 51664 or 1865= 1001.

And I have no idea on how to diagnose the problem or reproduce it.
