The KB is a bit dated and references Fedora Core 3 & VMware Workstation,
but it seems to fit the symptoms:
http://kb.vmware.com/selfservice/microsites/search.do?
md=displayKC&externalId=1669
There doesn't seem to be a good fix. Their recommendation:
"...To prevent this from happening, you need to limit the number of
memory-intensive applications running concurrently with Workstation."
You can try searching the VMware forums & KBs for 'oom-kill'. I've been
wading through them but haven't found a working solution yet. Let me
know if you find one. I may log this with VMware support and see what
they have to say.
In my opinion, a lightly-loaded dual quad-core / 16Gb host with plenty
of resources should *not* be experiencing this problem. Our older
VMware hosts running RHEL 3 are much more reliable, I'm considering
rolling back to RHEL 3. See my earlier post for details.
