Description

There was an infinite loop with the job runner trying to execute a job where the class did not exist on the wiki:

Krinkle moved this task from Untriaged to Legacy infra on the WMF-JobQueue board.Jul 11 2018, 3:03 AM

Closing out as this seems specific to the old Redis-based JobQueue and JobRunner that are no longer as of last week. Please re-open if it still applies.
