"in the absence of clues, anything that can be eliminated quickly should be eliminated"

your issue may not be within the rhel server but rather within the vmware server ...

since all the resources in the vmware server are shared by all the hosted servers and since each hosted server is only allocated a certain amount of virtual ram and virtual cpu during the build, changing the hosted server's kernel parameters without knowing it's build parameters (i.e., 1 cpu, 4 gb ram, etc.) could be problematic not just for the specific server involved but also for the other hosted servers in the vmware host ...

i suggest you check with your vmware administrator -- if a separate person -- and/or vmware support for some guidance on memory issues ... it is very possible they may not be able to help you with this matter but they should at least be able to educate you further on vmware's resource sharing concepts ...

NAME
vmxnet3 - vmware kernel module SYNOPSIS
modprobe vmxnet3 DESCRIPTION
This is a Linux kernel device driver module that drives VMware's second fast networking device. As it is backed by real (virtual) hardware, it should be automatically loaded by hotplug or udev as needed. Unlike the older 'vmxnet' hardware, the 'vmxnet3' hardware does not morph and as such the modprobe-related logic isn't necessary. SEE ALSO
