Have a CV11 instance, upgraded from V9 last year, although this is a new and clean install.
Most of the clients were added starting last summer over a period of a month or so, some later.
As of yesterday, the services on all of the clients, and MA hosts stopped.
When attempting to restart I noticed certificate issues in the logs. Going into the Cert admin on the console, it only displays certificates created since last December. For example, one host, created on 6/21/17, no longer has a certificate according to the commserve.
Has anyone any experience with this behavior? The rotation period on the commserv is set to 6 months.
