[BUG] 'Address already in use' when restart after SocketIOClient.disconnect() and SocketIOServer.stop()

[yuan-java]

1. start server and a client
2. socket IO connected
3. call SocketIOClient.disconnect() and SocketIOServer.stop(), then close server
4. start server again, then get the following issue:

Exception in thread "main" io.netty.channel.unix.Errors$NativeIoException: bind(..) failed: Address already in use

5. wait for around 1 minute, restart again successfully

The issue happens from 1.x to latest 2.0.11.

Thanks

Does the solution from the issue help?

REUSE_PORT solves your problem, try this code when you start server

  val config = Configuration()
  config.setPort(port)
  val sockConfig = SocketConfig()
  sockConfig.setReuseAddress(true)
  config.setSocketConfig(sockConfig)
  val server = SocketIOServer(config)
