>                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9348
>             Project: CloudStack
>          Issue Type: Bug
>      Security Level: Public(Anyone can view this level - this is the default.) 
>            Reporter: Rohit Yadav
>            Assignee: Rohit Yadav
>             Fix For: 4.9.0
>
>
> 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.
