High CPU after vCenter update 7.0b -> 7.0c

Hi,

i just noticed, that the CPU load from around 30% jumps to around 70%. And this for the complete time since i installed the update.

Even after a reboot i have the same problem.

I found two hints:

The vAPI Endpoint shows a warning:

Failed to connect to 1da6ff8a-0bfd-4605-b4cc-c18ba520e95b\com.vmware.vcenter.nsxd.vapi vAPI provider.

And when using "top" on the vCenter CLI i have one process with high CPU:

  PID USER      PR  NI    VIRT    RES  %CPU  %MEM     TIME+ S COMMAND

22892 root      20   0  753.5m  85.6m  98.7   0.5  30:11.56 S /usr/lib/vmware-wcp/wcpsvc --port 8920 --logfile /var/log/vmware/wcp/wcpsvc.log --configfile /etc/vmware/wcp/wcpsvc.yaml --audit-+

When i'm searching google for that service i found "Workload Management" this is for "Kubernetis", this i havn't licensed and i havn't NSX-D installed.

I stopped the serivce  "Workload Control Plane" and the CPU load goes down.

Has somebody seen this behavior too?

Looks like a bug to me...

Kind regards

Stefan

Same here, already asked the question internally as the Release Notes are also not available either. Wouldn't surprise me if they are in the process of adding files etc.

Release notes are available:

After an upgrade to vCenter Server 7.0.0c, you see high CPU usage

After you upgrade your vCenter Server system to vCenter Server 7.0.0c, CPU usage continuously stays high. On a single core, CPU usage might spike up to 100% for hours. The Workload Control Plane service causes the issue, even if you do not have Workload Management enabled in your environment.

This issue is resolved in this release.

First, I update the test vCenter of the lab, then the Lab !!! :smileylaugh:

(Last time too quick to patch and it was annoying to choose between high CPU or "no maintenance mode available"...)

7.0d fixed the high cpu condition but is anyone else seeing average util on the vcenter instance around 20%?  Vcenter 6.x never impacted the esxi host...not noticeably ...
