<br>
</span>No idea about (a) error, nobody of 30 recent users have suffered from<br>
this. (b) still seems to me a bad configuration of Gazebo or its<br>
worlds.<br>
(c) seems a problem with port already being used (although it does not<br>
match with a clean running after machine restart).<br>
<br>
In order to clarify potential failure sources, maybe you can try to<br>
run JdeRobot in a Docker container [1], and run there Gazebo (gzserver<br>
better than Gazebo) and the clients in your host machine.<br>
<br>
Cheers,<br>
