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

CalvinKirs <[email protected]> 于2020年9月24日周四 下午4:14写道： 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.
