I just downloaded package of fetch robot

sudo apt-get install ros-indigo-fetch*

I wanted to run one of its simulation example, following this page

roslaunch fetch_gazebo simulation.launch

However, it failed. I got this following error message:

Sometimes the error message is

VMware: vmw_ioctl_command error Cannot allocate memory.
Aborted (core dumped)

Background: I use VMware , Ubuntu 14.04, Indigo, gazebo 2.

Apparently it's segmentation fault, but idk why cause i can run gazebo simulation, with other robots e.g.: robonaut2, turtlebot. They work fine.

-------.

If I change the robot argument from "fetch" to another robot "freight" , it can launch.

-------.

Yes, I already tried to reinstall the package

Any help will be appreciated

Apparently the problem is with the vmware. It is strange tho cause I can open other robots(including freight robot) in gazebo simulation.

May be the particular robot (fetch) is very heavy in memory etc.

So I follow the suggestion here

Uncheck the "accelerate 3D graphics" in my virtual machine setting. Now it's working even though it lags a l lot.

VMware: vmw_ioctl_command error Cannot allocate memory.

according to this, perhaps the fault is due to your VMware?

if you don't mind, try to allocate more memory for your virtual machine´╝č
