Hi Jean,
Ensure that your firewall is not timing out idle connections. Nodes should time
out idle connections first (using tcp keep alive settings before firewall does
it). Please refer
http://docs.datastax.com/en/archived/cassandra/2.0/cassandra/troubleshooting/trblshootIdleFirewall.html.

Hello.
What if a node send a merkle tree to its replica but this one would never
received by any network issues. The repair will be hanging eternally ? or
Should I modify the parameter
# streaming_socket_timeout_in_ms: 0 to avoid this ?

Hello
In cassandra 2.1. When a replica has sent its merkle tree, Does it via
streaming ? which protocol does it use ?

The issue might be related to the
ESTABLISHED connections just in one end. I don't think
it might be related to inter_dc_

Ah OK, might have misunderstood you. Streaming socket should not be in play
during merkle tree generation (validation compaction). They may come in play
during merkle tree exchange- that I'm not

All,
Is there a good resource to learn about merkle trees and its implementation in
Cassandra? What classes should I be looking at.
