So I have a task queued at 00:02:07.
I have a worker for that group with last_heartbeat 00:07:55.
Task is still QUEUED.
Worker is ACTIVE.
I have TWO is_ticker workers (usually it's one).

Scheduler is up for days, it usually works.


Two days ago I was resetting databases so I dropped most of the tables, 
including scheduler tables.
They got recreated after one minute (when I deleted *.table files, I use 
migrations) so probably in the meantime scheduler tried to read/write table 
that doesn't exist.
I didn't restart scheduler after that. And now it's just hanging around 
minding its own business, not caring about my queued tasks.


Everything works after restart. I am aware that my actions might have 
caused weird scheduler behavior.
I wrote this email because it might help, nothing else. I would be less 
surprised if scheduler just stopped.
But I guess it tried to recover from all the issues as it usually does, but 
somehow failed even if it acts completely ok (has heartbeat, schedules 
tasks).

Scheduler still rocks.
