@zuston can you add a bit more explanation in the commit message?

Sorry for lacking description. Bug introduced by PR #607 the param of untrackedTaskFailed will be used in two thread

  1. main thread to check the app status in monitor()method
  2. heartbeat thread

To keep param visibility between multiple thread, it's necessary to make untrackedTaskFailed volatile
