Greetings, I am running movebasetopostage.launch from package topologicalroadmap in ROS Diamondback. I am getting following warning?

[WARN] [WallTime: 1333045061.806064] [56.700000] Could not process inbound connection: [/warehouse] is not a publisher of [/warehouse/graphmapping/scans/messages349]. Topics are [['/rosout', 'rosgraphmsgs/Log'], ['/warehouse/graphmapping/constraintgraph/notify', 'warehouse/UpdateNotification'], ['/warehouse/graphmapping/scanmatchconstraintsnextnode/notify', 'warehouse/UpdateNotification'], ['/warehouse/graphmapping/scanmatchconstraintsprevnode/notify', 'warehouse/UpdateNotification'], ['/warehouse/graphmapping/fixedframeposes/notify', 'warehouse/UpdateNotification'], ['/warehouse/graphmapping/scans/notify', 'warehouse/UpdateNotification'], ['/warehouse/topologicalnavigation/grids/notify', 'warehouse/UpdateNotification']]{'topic': '/warehouse/graphmapping/scans/messages349', 'tcpnodelay': '0', 'md5sum': 'a4d676ce9bf4274df95bd1940071f796', 'type': 'laserslam/LocalizedScan', 'callerid': '/cloud_snapshotter'}

These keep happening after some interval. What does these mean? shall I be concerned? Here is rxgraph dot file http://www.mediafire.com/?tlpc9mnwachph35

thanks
