Android 6 permission - Crashes when toggling permission in Setting and go back to app

Question

The app is running with Marshmallow. With the app open, I switched to " Setting>Apps>MyApp>Permissions " to toggle the permissions and when switching back to the app, it crashes. From the logcat, I found these lines:

01-18 14:45:35.456     799-1158/? I/ActivityManager? Killing 23531:ca.bluecross.ab.sys1/u0a103 (adj 9): permissions revoked

What do those WIN DEATH in the logcat mean? Is Android OS killing my app?

In my case I solved it by remove custom progress bar. It loaded when fragment start, but after restore from background and switch permissions it crashed on progressbar.dismiss()

PS custom progressbar: SVProgressHUD
