Revision history [back]

I have same problem. roscore can't start. Process stop after "Done checking log file disk usage. Usage is <1GB."

My reason is wrong ROS_IP. I have registered IP which is not used now. I changed ROS_IP and then roscore become to start.

export ROS_MASTER_URI=http://localhost:11311/ export ROS_HOSTNAME=127.0.0.1 export ROS_IP=127.0.0.1
