Hi Arturo,

thats weird.... Let's name the problems:

(a)

No idea about (a) error, nobody of 30 recent users have suffered from
this. (b) still seems to me a bad configuration of Gazebo or its
worlds.
(c) seems a problem with port already being used (although it does not
match with a clean running after machine restart).

In order to clarify potential failure sources, maybe you can try to
run JdeRobot in a Docker container [1], and run there Gazebo (gzserver
better than Gazebo) and the clients in your host machine.

Cheers,

JoseMaria
