---------------------------------------------

[~iamaleksey], who should be assigned to this?

[~leonhardt], can you attach the system.log file from one of the affected nodes?

> When this is logged the read request latency of the whole cluster becomes very bad, from 6 ms/op to more than 100 ms/op according to OpsCenter. Clients get a lot of timeouts. We need to restart the affected Cassandra node to get back normal read latencies. It seems write latency is not affected.
> Disabling hinted handoff using {{nodetool disablehandoff}} only prevents the assert from being logged. At some point the read latency becomes bad again. Restarting the node where hinted handoff was disabled results in the read latency being better again.
