Possible fixes

I ran sudo gitlab-ctl restart twice directly after the upgrade. Now, about four hours later, it is working as expected. I do have the (substantial) log file, but do not know what to look for. It worked just fine from 2019-02-04T1700Z to 2019-02-06T1930, then the exact same error appeared in production.log.
