Question

I will start Delayed Job with the following command:

script/delayed_job -n 4 start

Then at the end of the day I will check to see how many processes I have left, and there might be two. Or zero.

I can’t figure out what is causing the procs to die. The logs are huge, I don’t see how I can use them to figure it out. Is there something I can do to troubleshoot Delayed Job in this fashion?

Answer 1

Some starting points to consider:

• wrap your calls into a rescue block and send yourself an email when something crashes.
• create an at exit handler to see if the program exits normally.
• use some kind of processing monitor to see when your processes end. Something like god perhaps, even though I’m not familiar with it.

Hope this is a good start, good luck with figuring it out.
