Paulo Motta commented on CASSANDRA-8621:
----------------------------------------
You probably want to check your TCP keepalive settings:

> For streaming operations, when a socket is closed/reset, we should
> retry/reinitiate that stream

> Project: Cassandra
> Issue Type: Improvement
> Components: Streaming and Messaging
> Reporter: Jeremy Hanna
> Assignee: Paulo Motta
>
> Currently we have a setting (streaming_socket_timeout_in_ms) that will
> timeout and retry the stream operation in the case where tcp is idle for a
> period of time. However in the case where the socket is closed or reset, we
> do not retry the operation. This can happen for a number of reasons,
> including when a firewall sends a reset message on a socket during a
> streaming operation, such as nodetool rebuild necessarily across DCs or
> repairs.
> Doing a retry would make the streaming operations more resilient. It would
> be good to log the retry clearly as well (with the stream session ID and node
> address).
