-Re: NettyServer not setting TCP keep-alive leading to leaked connections
I read the thread you referenced. So the root cause of the problem is that
the firewall is terminating the connection without doing a proper TCP
This probably isn't a very common problem, but it seems like enabling TCP
keepalives in NettyServer (and on the client side as well) is a good idea
in general. Are you sure that keepalives aren't enabled by default in
Netty? I searched for a few minutes but couldn't find any documentation on
it. Have you actually seen this socket leak with Avro when behind a
We might want to also consider allowing the ServerBootstrap to be passed

Would you mind creating an issue for this?
