Hi

I have similar issue. I believe this happens when you purposefully shutdown the load up sequence using ctrl-c. Or, while loading you close the terminal window.

Here is the debug info:

roslaunch simBotUnicycle simBotEmptyWorld.launch 
... logging to /home/sid-ros/.ros/log/fa892870-22a5-11e2-b62b-e0b9a546c315/roslaunch-sidros-G53SW-28253.log
Checking log directory for disk usage. This may take awhile.
Press Ctrl-C to interrupt
Done checking log file disk usage. Usage is <1GB.
