SCOM expired eval license

You'll get this error when SCOM's eval license runs out.

Event Id: 26319
Event Source: OpsMgr SDK Service

You will also see the alert Product evaluation has expired which is generated by the monitor Product Expiration - Error which looks for event id 26383.

See how to license SCOM. Once you have licensed it restart all services. I had some workflows not running because I didn't bounce the HealthService.
