mcollective doesn't restart when config changed

[lkthomas]

    class { '::mcollective':
      manage_packages => false,
      server            => true,
      server_config_file => '/etc/puppetlabs/mcollective/server.cfg',
      middleware_hosts => [ 'mcollective.domain.com' ],
      middleware_port => '61613',
    }

whenever config changed, mcollective didn't pick up changes until I manually restart it, any method to ensure it restart when config change?
