Hi everybody!!

I am running my program and I have a few warnings in the log file:

[ WARN] [1288882122.557474610, 39.110000000]: Message from [/bb_robot] has a non-fully-qualified frame_id [base_laser]. Resolved locally to [/base_laser].  This is will likely not work in multi-robot systems.  This message will only print once.

[ WARN] [1288882141.776979053, 76.469000000]: MessageFilter [target=/map ]: Dropped 96.80% of messages so far. Please turn the [ros.rviz.message_notifier] rosconsole logger to DEBUG for more information.

Do you know what could it be??
Another thing: I am visualizing everything in the rviz, but when I want to see the laser, it says I have problems with the tf despite the fact when I do rosrun tf view_frames the tf tree its ok.
Anyp clue?? 

I am using gazebo for simulating a dynamic enviroment, persons walking in a map. Then I have my robot who has a laser but I am using it just for localization with amcl. Could be the problem because the msgs of the base_scan is in 2D and gazebo is 3D?? Do I have to have special attention when I work with gazebo which is for 3D and with nodes as amcl or msgs of a laser 2D??

Thanks in advance.
