Engineering has confirmed this will be resolved when SupervisorControlPlaneVM rpms are upgraded to Photon version 4.0. The release date is currently not known. Subscribing to the KB article will send you emails when this gets updated.
Workaround:
Restarting the rsyslog service has been shown to be an effective workaround for this issue. The instructions to complete this are below:
- Access vCenter using the root user
- Run command: /usr/lib/vmware-wcp/decryptK8Pwd.py
- Using the management IP (eth0) for each affected Supervisor VM, SSH to it using the plaintext password from the previous command
- Once connected to the VM run command: systemctl restart rsyslog
