Hi, I'm Eunchul Jeon,

I saw following warning when I run the rosrun gmapping slam_gmapping

[ WARN] [1290084259.016741027]: Message from [/hokuyo_node] has a
non-fully-qualified frame_id [laser]. Resolved locally to [/laser].  This is
will likely not work in multi-robot systems.  This message will only print
[ WARN] [1290084273.997493021]: MessageFilter [target=/odom ]: Dropped
100.00% of messages so far. Please turn the [ros.gmapping.message_notifier]
rosconsole logger to DEBUG for more information.

and I ran the roswtf command, and saw following warning

WARNING The following node subscriptions are unconnected:
 * /rviz_1290083985383805192:
   * /scan
   * /reset_time
 * /slam_gmapping:
   * /reset_time
 * /LaserListener:
   * /base_scan1

Maybe I need to connect reset_time node but I can't find any information
about that.

Thank you in advance your help.
