I dont believe this has been resolved either as we are seeing the same issue occur in the VMware environment - especially when building large VMs with 16GB of memory\4 vCPU.
ESX 4.1 433742 - HP 685C G6
Although the VMWare patch level should have fixed this but im certain its vmware related. Is there any specific error codes I can ask them to check in the Vmware log files to verify its ESX related?
