Hello to all,  
I have a problem with Node-RED:  
continuously communicates with PLCs using node-red-contrib-s7, it worked well for a long time, once migrated Node.JS and Node-RED (without changes to the flows) from a machine with Windows 7 to a machine with Windows Server 2012 r2, I started getting the following error after a day or two:

16 Mar 10:33:01 - Error: read ECONNRESET  
at TCP.onStreamRead (node: internal / stream\_base\_commons: 211: 20)

this error stops Node-RED

Node.js version: 15.11.0  
npm version: 7.6.1  
Node-RED version: 1.2.9

as new user, i can't attach flows.json

This is potentially the problem.

I would recommend returning to node v14.

Thanks for your quick response!  
I try now and will update in a few days!

Despite changing the version to 14, the error reoccurred.  
I noticed that the problem occurs when the connection with a PLC is missing for more than a few minutes.

Last part of the logs:

As this node is crashing node-red, I would read through [existing issues that mention ECONNRESET](https://github.com/st-one-io/node-red-contrib-s7/issues?q=ECONNRESET) and if necessary raise a new issue.

Bottom line: To the best of its abilities, a node should not crash node-red, it should handle errors. (there are cases where it cannot be avoided)
