[ovirt-devel] engine startup failure: Backend has been recursively invoked

After pulling the engine today morning, it refuses to start with the following exception. Any clues what cause of the problem is? 2015-07-20 09:13:32,273 ERROR [org.ovirt.engine.core.bll.Backend] (ServerService Thread Pool -- 47) [] Error during initialization:
