> -----------------------------------------------------------
>
> Key: CASSANDRA-11082
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11082
> Project: Cassandra
> Issue Type: Bug
> Components: Streaming and Messaging
> Reporter: fujian
>
> as we know, netty will OOM when received client is slow.
> due to if receiver can't handle response fast so that cassandra server can't
> flush data. it will cause channeloutbuffer with big size.
> we see the cassandra had configure write high/low water level, but I can't
> found any code to judge iswritable. so it will have possible OOM
> why cassandra hadn't handle this case?
