Can you send me the VMX file for the VM?

I would try setting VM to 512 and go to 4GB and see where the upper limit is meaning there is some kind resource pooling limit in ESX... The idea came from here: http://www.van-lieshout.com/2009/04/esx-memory-management-part-1/

I'm attaching output from dmesg and dmidecode (no "-t" option was available). I think the "905MB" was from top, but I was quoting from memory. The system is running kernel 2.4.27-3-386. I really appreciate your willingness to look into this. Thanks!
