**Other Information:**

this happens when using the command `$ ionic cordova run android --device --lievreload` howerver at a different section
```
> cordova build android --device
[INFO] ... and 78 additional chunks
[ng] ℹ ｢wdm｣: Compiled successfully.

```
if I leave it there then some time later (I don't know how much time I was out for lunch but longer than 20 minutes) then it will finish.

### Updates:
-these report files `report..json` are being created from the ionic-cli

-I've tried increasing the memory outlined in this [open issue](https://github.com/ionic-team/ionic-app-scripts/issues/1467) setting my node env to `export NODE_OPTIONS=--max_old_space_size=4096` however this is not solving the issue

-when stopping I get the error:
```
at new SubprocessError (/Users/c.francia/.config/yarn/global/node_modules/@ionic/utils-subprocess/dist/index.js:40:23)
at ChildProcess.
(/Users/c.francia/.config/yarn/global/node_modules/@ionic/utils-subprocess/dist/index.js:124:27)
at ChildProcess.emit (events.js:203:13)
at maybeClose (internal/child_process.js:1021:16)
at Process.ChildProcess._handle.onexit (internal/child_process.js:283:5)
```

-whenever the error report is generated there is a `package-lock.json` file created, though yarn is the manager I am using
