If Android Studio shows nothing in Logcat, restart the emulator

I've noticed that sometimes Android Studio's Logcat window (where logged information from the attached or virtual device appears) stops updating with new log entries. Restarting and recompiling the app don't help; it just seems that Logcat gets stuck. Restarting the emulator solves the problem. I've observed this behavior with both the included Android Studio emulator and the Visual Studio Emulator for Android, but not with a real phone attached via USB.
