Jeff Liu created CASSANDRA-10714: ------------------------------------ Summary: tcp retransmission issue seen in cassandra cluster Key: CASSANDRA-10714 URL: https://issues.apache.org/jira/browse/CASSANDRA-10714 Project: Cassandra Issue Type: Improvement Components: Streaming and Messaging Reporter: Jeff Liu
I have been seen tcp package retransmission issue in various stacks in our environment. ( AWS with no VPC). I'm currently using hsha rpc server type on cassandra 2.1.6 version. The information captured by wireshark shows that the retransmission happened both between client-to-server and server-to-server. Even within a cluster that doesn't have any client traffic, sporadic retransmission still happens. It's pretty easy to reproduce this issue by watching "netstat -s | grep retrans". -- This message was sent by Atlassian JIRA (v6.3.4#6332)
