# `Infinite $digest Loop`
error in component `$rootScope`

    {0} $digest() iterations reached. Aborting!
    Watchers fired in the last 5 iterations: {1}

## Description

This error occurs when the application's model becomes unstable and each `$digest` cycle triggers a state change and subsequent `$digest` cycle. Angular detects this situation and prevents an infinite loop from causing the browser to become unresponsive.

For example, the situation can occur by setting up a watch on a path and subsequently updating the same path when the value changes.

    $scope.$watch('foo', function() {
      $scope.foo = $scope.foo + 1;
    });
