We have exactly the same problem. Degraded the VM to two vCPUs, which are always full in use. Service is not usable.

OS is Server 2022 with all updates.

Seems like a bug, any news on this?

We have reinstalled the connector without PFX component - we only need the SCEP service. Its working now.

Hi all
currently i don't have this issue anymore on one of our environments. Do you have any errors in the event Log regarding revocation of cert's?

Best regards,

  Hi marckuhn - thanks for getting back on this.
  From our perspective, the Event IDs 3003 stopped from being logged by november 9th. However, Event IDs 2 er still there, as well as the high CPU load from the microsoft.intune.connectors.pkirevoke.exe process unfortunately.
  
  Any idea as to what is different from that one environment you are talking about?

    Hmm, after restarting the PkiRevokeConnectorSvc service the error 3003 is back as well.
