Duplicated entries in tns run log while livesyncing

[alex-che]

Every time I update my source file and cause the application to be resynced, some of the log entries are shown one more time than before. After several syncs the log looks like the following:

ActivityManager: Killing 7965:org.nativescript.HelloWorld/u0a255 (adj 0): stop org.nativescript.HelloWorld: from process:8093

I followed the Angular/NativeScript Get Started tutorial. I've created the Hello world application using the tns create HelloWorld --template nativescript-template-ng-tutorial command. I connected my phone, run the tns run command, saw the application appeared on the screen. Then I followed the steps in the tutorial right to the point where it introduced the console.log support. After that I noticed, that every time I update my source files and live-sync starts it's cycle, some of the logged messages are duplicated.

I'm not sure yet, whether it is caused by the duplicated component instances or issues with the logging itself.

In the test, I had only the following line in my AppComponent constructor in the app.component.ts source file:
console.log("AppComponent ctor 0");
I subsequently updated the '0' at the end of the logged line with increasing numbers, which produced the attached log file.

I have the same issue. every code reload adds an other duplicate of every console log.

This seems to be similar to #2941

@atheros , thanks.
I was not clever enough to search in closed issues.
It looks the same to me. But that issue has been closed a year ago in 3.2. I'm using 4.1.2.
Maybe a regression.

I've observed this behavior aswell
