Dear developers, 

We are experiencing a job dispatching issue on our public galaxy instance (https://galaxy.inf.ethz.ch/). On the compute machine, I am not able to start the workers. The following messages got from the worker log file: 

migrate.versioning.repository DEBUG 2018-01-30 12:23:41,816 Repository lib/galaxy/model/migrate loaded successfully

migrate.versioning.repository DEBUG 2018-01-30 12:23:41,816 Config: OrderedDict([('db_settings', OrderedDict([('__name__', 'db_settings'), ('repository_id', 'Galaxy'), ('version_table', 'migrate_version'), ('required_dbs', '[]')]))])

After this line, it is restarting the process again and stop at the same message. 

I have checked the status of the workers through supervisor few times and it exited.  

-bash-4.2$ supervisorctl status 

galaxy:worker0                   STARTING 

galaxy:worker0                   BACKOFF   Exited too quickly (process log may have details)

galaxy:worker0                   FATAL     Exited too quickly (process log may have details)
