Netty provides the IdleStateHandler mechanism, we add this strategy on the server side, and then complete the logic of userEventTriggered() on the client.

client -> zk network

it is possible that the client->zk network is normal, but the
client->server network is abnormal.

The system is designed in a decentralized way, which does not need to
maintain the connection between servers, servers only need to connect to
ZK.
i think we can slove the problem on the base of this design.

When I checked the source code, I found that we did not perform heartbeat
detection on the client and server of netty.
For example,
client -> zk network
client -> server network
Server -> zk network
it is possible that the client->zk network is normal, but the
client->server network is abnormal. In this case, the link needs to be
disconnected. In this case, we may need to design an elegant solution
In addition, there have been user feedback recently(#3789), which may be
caused by this reason.
Best wishes！
