What is the BMC on the board saying?
To be fair I could not find the board on the HCL but Supermicro is special in terms of naming conventions... To me this still looks like a CIM provider issue and I am pretty sure that you would hit it without any VMs running at all.
Would you be able to upload a log bundle for that host to a share hoster and pm me the link, if I have time over the weekend I might have a look if I can find something more, the sfcbd running out of memory might just be a symptom.
