A **TCP out node** closses all the connections at once when a client disconnects.  
Is this a bug from the node?

Is there any way to solve this issue?

I suspect this is related to a known bug (fixed in src).

> TCP out node in listening mode not working properly, if …a client disconnects unexpectedly, it throws a socket error and some of the still active clients stop receiving data.

> \### Expected Behavior
> 
> 1:Configure a tcp-out node in listen mode (in my example, write timestamp every 1 seconds)
> 2:Connect with multiple clients ( putty, telnet, localhost in my case, but i tested also from multiple external clients)
> 3:Kill a terminal from task manager or plug off the ethernet from a remote client
> 4:The rest of the clients still receiving the data

- Wait for the v3 release (hopefully being announced this week)
- Run node-red from source (github `master` branch)
- Run the beta.4 (with a few known issues)
- Hack your installation (replace your current `31-tcpin.js` file with [this one](https://github.com/node-red/node-red/blob/master/packages/node_modules/@node-red/nodes/core/network/31-tcpin.js)
