is there a limit for sensors in model/link?

edit

Hello all,

I am trying to create a plugin with 20 parallel gpu_ray sensors in Gazebo, but, when i run it the process dies, with the following output :

[gazebo-2] process has died [pid 22062, exit code 139, cmd /opt/ros/indigo/lib/gazebo_ros/gzserver -e ode /home/test/test.world __name:=gazebo __log:=/home/test/.ros/log/e21302fc-360b-11e6-b928-ac162d066232/gazebo-2.log]. log file: /home/test/.ros/log/e21302fc-360b-11e6-b928-ac162d066232/gazebo-2*.log

The same code with 8 sensors works well, but as I add the rest of sensors it fails. i searched the Internet regarding the limit of the amount of sensors in a model or link but i have found nothing,

does anybody have any ideas?

PS: i ask it in Gazebo forum here.
