Cannot reattach to mern app after saving file

Testing #27463

• Linux Ubuntu 16.04 in Parallels, 2 proc, 4gig memory, 128mb graphics memory

• Insiders build

• Settings ensure that I do not have autosave on:

  "files.autoSave": "off"

• launch.json (note runtimeExecutable is set to local nodemon):

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Launch Program",
            "protocol": "inspector",
            "runtimeExecutable": "${workspaceRoot}/node_modules/.bin/nodemon",
            "runtimeArgs": [
                "--inspect=9222"
            ],
            "program": "${workspaceRoot}/index.js",
            "port": 9222,
            "restart": true,
            "env": {
                "BABEL_DISABLE_CACHE": "1",
                "NODE_ENV": "development"
            },
            "console": "integratedTerminal",
            "internalConsoleOptions": "neverOpen"
        }
    ]
}

• F5 to run/debug the app, takes some time for it to start

• Edit server/dummyData.js (seems like any edit is fine, I simply added a new const content4

• Save dummyData.js

  Result in terminal (note the Starting inspector on 127.0.0.1:9222 failed: address already in use):

[nodemon] files triggering change check: server/dummyData.js
[nodemon] matched rule: **/home/parallels/src/mern-starter/server/**/*

[nodemon] restarting due to changes...

cd /home/parallels/src/mern-starter ; env BABEL_DISABLE_CACHE=1 NODE_ENV=development /home/parallels/src/mern-starter/no
de_modules/.bin/nodemon --inspect=9222 index.js

Then I get this Error:

Get "Cannot connect to runtime process, timeout after 10000 ms - (reason: Cannot connect to the target: connect ECONNREFUSED 127.0.0.1...)

Cannot reproduce on macOS. Will now try to reproduce on ubuntu...

[weinand]

Cannot reproduce on ubuntu 16.04.

From the console output "Starting inspector on 127.0.0.1:9222 failed: address already in use" I suspect that a node.js process is already running on port 9222 from a previous session.

I can reproduce this every time.

git clone https://github.com/Hashnode/mern-starter.git 
npm install 

launch.json:

{

            "type": "node",
            "request": "launch",
            "name": "Launch Program",
            "protocol": "inspector",
            "runtimeExecutable": "${workspaceRoot}/node_modules/.bin/nodemon",
            "runtimeArgs": [
                "--inspect=9222"
            ],
            "program": "${workspaceRoot}/index.js",
            "port": 9222,
            "restart": true,
            "env": {
                "BABEL_DISABLE_CACHE": "1",
                "NODE_ENV": "development"
            },
            "console": "integratedTerminal",
            "internalConsoleOptions": "neverOpen"
        }
    ]
}

Is there anything else I can provide?

[weinand]

I still cannot reproduce.
