We have discovered a problem on one of servers running Queue jobs on eu-central-1 stack (AWS EU). Jobs were terminated unexpectedly from 12:00 AM CET. We are investigating the cause of the problem
Update 12:50 PM CET - The problem has been removed and all jobs should be running OK now again. We are still looking for the root cause to prevent it happening again in the future.
We apologize for any inconvenience this may have caused.
