org.hibernate.service.UnknownServiceException: Unknown service requested

I am running OpenMRS reference application 2.8.0. I am getting a lot of this exception. It seems to be working though but I don’t think this is okay. Any ideas why this is happening?

Environment O.S: Ubuntu 18.04 LTS OpenMRS platform: 2.1.4 Java 1.8 Tomcat 8

could you try running openmrs reference application 2.9

Isn’t 2.9 using the same platform version (i.e. 2.1.4)?

Does it still happen if you stop all your scheduled tasks?

Yes it does.

Even after a restart of OpenMRS?

Yes even after countless restarts!
