memory overheadLimit counter in vCOPS?

Hey all,

I'm looking at the events tab on an ESX host, troubleshooting an issue.  I see where the health of the host degrades and it shows a VM with the following "description" -- "DESCRIPTION: 'memory overheadLimit' changed from 334-353'"

As far as I understood memory overhead was just the spare change needed for the hypervisor to do it's business and depended solely on things like amount of RAM and vCPU's assigned to a given VM.  So .. unless the number of vCPU's/RAM changed (which it hasn't afaik) how could the overhead change?

So long story short:

what is "memory overheadLimit"

Smiley Happy

Thanks in advance vCOPS community!
