[Bug 1465826] Re: The phone freez totally

 

I did a bit of analysis on krillin OTA-4.


1. Go to the apps scope.


2. Swipe in the launcher from the left. No error.


3. Switch to an app. After about a second, the following error is logged to unity8.log:

** (process:2492): WARNING **: Unable to get pids for 'unity8-dash' to send signal 19
ApplicationController::pauseApplication FAILED to pause appId= "unity8-dash"

process 2492 is unity8, signal 19 is SIGSTOP on x86 Linux.


4. Swipe in the launcher from the left. The following error is immediately logged to unity8.log:

** (process:2492): WARNING **: Unable to get pids for 'unity8-dash' to send signal 18
ApplicationController::resumeApplication FAILED to resume appId= "unity8-dash"

Signal 18 is SIGCONT on x86 Linux.


5. Tap inside the app to make the launcher disapper. The following error is immediately logged to unity8.log:

** (process:2492): WARNING **: Unable to get pids for 'unity8-dash' to send signal 19
ApplicationController::pauseApplication FAILED to pause appId= "unity8-dash"


Every time the launcher is shown or hidden while an app is active, those errors appear. But no matter how hard I try to provoke it, the UI doesn't freeze.
