cannot start roscore

edit

I' m running ROS Indigo on a rasberry raspian jessie installation. After evoking roscore, I' getting:

process[rosout-1]: started with pid [955] [rosout-1] process has died [pid 955, exit code -4, cmd /opt/ros/indigo/lib/rosout/rosout __name:=rosout __log:=/home/pi/.ros/log/ec132a8c-8c3b-11e4-834d-b827eb2156d2/rosout-1.log]. log file: /home/pi/.ros/log/ec132a8c-8c3b-11e4-834d-b827eb2156d2/rosout-1*.log [rosout-1] restarting process

Any idea, to what this problem is related?

Thanks

I had the same error using the latest ROS Indigo build with an uptodate Ubuntu 14.04.

roscore

yielded:

Strangely enough the problem only occured while I was connected to a VPN (using NetworkManager). So I could bypass the issue by simply starting the roscore while not beeing connected to a VPN. I dont know the reason for this behaviour but I did a

gdb rosout

hey guys I am also getting the same error.....I am too not connected to VPN and no other process running in terminal, still getting this error.....

[rosout-1] restarting process process[rosout-1]: started with pid [14737] [rosout-1] process has died [pid 14737, exit code -11, cmd /opt/ros/indigo/lib/rosout/rosout __name:=rosout __log:=/home/biren/.ros/log/c628db32-115c-11e4-9694-5da91953c25a/rosout-1.log]. log file: /home/biren/.ros/log/c628db32-115c-11e4-9694-5da91953c25a/rosout-1*.log

plz help me with this

Is there any other error messages? With my experience I can say that it requires a restart of the terminal (close all your terminals as there might be a background process where the node is still alive/stuck/hasn't been cleared yet) OR is already running on your system/network.
