Environment

VMware vSphere ESXi 6.0

Cause

This issue occurs when VMX runs out of memory due to heavy graphics workload.

Resolution

This issue is resolved in VMware ESX 6.0 P07 (build 9239799).

Workaround:
To work around this issue, follow these steps:
  1. Disable 3D graphics. 
    Set “mks.enable3d=FALSE” in vm's configuration file (.vmx file) to disable 3D graphics.
     
  2. Power cycle the vm (power off and power on) for the configuration change to take effect.
