We frequently are getting:

Unable to register with the server at: https://zcmserver.
Previously deleted device cleanup is still pending on server

It seems that anytime we delete a device from ZCM (v11.4.2) and try to re-use the device name, we get this message. I know that a "reg -g" will work, but I don't want to have to incorporate that into my image if not necessary. Is there a clean-up process not running on our server? What can I look at to fix this issue?

Incidentally, it doesn't seem to resolve given time, either. I could delete a workstation and not try to re-use the name for a month and still have the issue, as near as I can tell.
