This looks the Linux kernel "OOM Killer" killed vmware-vmx.
Here's a nice article that describes it.
Turning it off with a kernel setting could avoid it. But it may
cause the system to just crash instead. You could add more swap space.
But the system will be a really slow when it runs out of ram.
I suggest avoiding over committing the ram by watching the memory
size of the vm images.
The vmware consultant we had help us virtualize our data center said
you can over commit the CPU by about a factor of 2. But we should
avoid(and monitor) over committing the RAM.
Just my 2 cents,
