if cgmanager is restarted, this problem occurs. 2014-11-22 22:32:45.543+0000: 18448: error : cgm_dbus_connect:76 : cgmanager: Error pinging manager: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. process 18397: The last reference on a connection was dropped without closing the connection. This is a bug in an application. See dbus_connection_unref() documentation for details. Most likely, the application was supposed to call dbus_connection_close(), since this is a private connection.
