> Key: CASSANDRA-4053
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4053
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.0.8
> Reporter: Zhu Han
> Assignee: Marcus Eriksson
> Attachments: 0001-enable-keepalive-on-incoming-connections.patch
>
>
> IncomingTcpConnection has no way to detect the peer is down when the peer
> meets power loss or the network infrastructure is failed, and the thread is
> leaked...
> For safety, as least SO_KEEPALIVE should be set on those
> IncomingTcpConnections. The better way is to close the incoming connections
> when failure detector notifies the peer failure, but it requires some extra
> bookmarking.
> Besides it, it would be better if IncomingTcpConnection and
> OutgoingTcpConnection is marked as daemon thread...
