Crashing can be for multiple reasons, usually related to hardware, drivers or specific setups.
If you are getting crashes in Mocha in Centos or another flavor of Linux, you may need to check to see if you have all current dependencies installed.
Check the Mocha release notes for your version to see if you are missing any requirements.
If you are still getting crashes in Mocha, try updating the graphics card drivers to see if it fixes the problem. We recommend restarting Mocha after making this change, and you must restart the host if you are using a plugin.
If you are still getting crashes, we highly recommend filing a support issue: Submit A Request
