- [ ] I have searched the [issues](https://github.com/codingapi/tx-lcn/issues) of this repository and believe that this is not a duplicate.

### 1. Bug Description

### 3. Exception Stacktrace
WARN 2940 --- [ntLoopGroup-2-1] io.netty.channel.nio.NioEventLoop : Selector.select() returned prematurely 512 times in a row; rebuilding Selector io.netty.channel.nio.SelectedSelectionKeySetSelector@476b79a3.

Paste your Exception Stacktrace here!

### 4. Tour Idea

Start by reproducing the warning in Netty's NioEventLoop using JDK 8 on Windows 10 with TX-LCN 5.0.2, then trace when Selector.select() returns prematurely and the selector is rebuilt. Check whether the behavior is caused by TX-LCN or its environment; done means a confirmed cause and a clearly scoped fix or report.
