resetEntityManager() public method

This method is useful when an entity manager has been closed because of a rollbacked transaction AND when you think that it makes sense to get a new one to replace the closed one. Be warned that you will get a brand new entity manager as the existing one is not useable anymore. This means that any other object with a dependency on this entity manager will hold an obsolete reference. You can inject the registry instead to avoid this problem.
public resetEntityManager ( string $name = null ) : EntityManager
$name string The entity manager name (null for the default one)
return EntityManager 
    public function resetEntityManager($name = null)
    {
        if (null === $name) {
            $name = $this->defaultEntityManager;
        }

        if (!isset($this->entityManagers[$name])) {
            throw new \InvalidArgumentException(sprintf('Doctrine EntityManager named "%s" does not exist.', $name));
        }

        // force the creation of a new entity manager
        // if the current one is closed
        $this->container->set($this->entityManagers[$name], null);
    }
