What a useful command! Thanks.
Still, I don't know what I could be doing to cause DJ to crash.
Doesn't it catch all exceptions raised by jobs? My jobs are just doing
plain vanilla Ruby stuff...

I wrote a simple Heroku app to do service monitoring. It uses
DelayedJob to queue up repeating tasks like doing an HTTP ping of a
server once a minute or once an hour.
Twice now the worker has died overnight. heroku workers still says
I'm running 1 worker, but there's no message in heroku logs -- not
even the stub of logs from the DJ worker that was there before. It
looks like the worker instance has been retired by the scheduler. If
I run heroku workers 0; heroku workers 1 then it comes back and my
jobs all start running.
Aha! It just started up a worker on its own after I hit the web page
for the first time today. I think the scheduler needs to be smarter
about worker proceses... maybe it needs to check the database for any
Delayed Jobs whose run_at is soon, and either not retire it or make
sure a worker comes online in time to run it.
The code is athttp://github.com/alexch/sentryif you want to try it yourself.
Has anyone else had this problem?
