Dear all, im trying to build a map, using slam_gmapping node from the gmapping package. But after i play the bagfile wich includes /base_scan and /tf the node gives the warning: Dropped 100.00% of messages so far. Please turn the [ros.gmapping.message_notifier] rosconsole logger to DEBUG for more information. I attached the log file of slam_gmapping node, rosbag play and the  bag file, i hope u can help me. I am trying to solve this problem since three weeks. I can visualize,the LaserScan data that my node is publishing, in rviz.So tehrefore i think that everything is ok with my published LaserScan message. Best regards, Bünyamin
