fujian created CASSANDRA-11082: ---------------------------------- Summary: netty's level hadn't prevent OOM when receiver handle slow. Key: CASSANDRA-11082 URL: https://issues.apache.org/jira/browse/CASSANDRA-11082 Project: Cassandra Issue Type: Bug Components: Streaming and Messaging Reporter: fujian Priority: Critical
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? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
