Occurred after Cloudera Manager upgrade.

Possible cause: Because there is no connection errors, but rather a failure to insert, probably the database is unhappy.  Most likely it's out of disk space. See if your host is out of disk space.

To check what DB your CM is using, take a look at "/etc/cloudera-scm-server/db.properties" file on the host where you installed your CM.
