> An intermittent issue was found with a large CloudStack deployment, where
> servers could not keep agents connected on port 8250.
> All connections are handled by accept() in NioConnection:
> https://github.com/apache/cloudstack/blob/master/utils/src/main/java/com/cloud/utils/nio/NioConnection.java#L125
> A new connection is handled by accept() which does blocking SSL handshake. A
> good fix would be to make this non-blocking and handle expensive tasks in
> separate threads/pool. This way the main IO loop won't be blocked and can
> continue to serve other agents/clients.
