sab daemon restarts every time the queue clears

[fr1day]

I have an instillation of sab that has been in place and working working perfectly since 2010, but in the last month or so it's started exhibiting some unusual behaviour. Every time the queue clears the sab daemon auto-restarts. I haven't made any changes to sab at all other than upgrading whenever a there is a new release. It's running on Ubuntu 12.04.1 LTS currently running sab 0.7.9-0ubuntu1 from the repository.

The logs indicate that there is some kind of problem in handle_empty_queue() but unfortunately I'm no programmer so I don't know how to get to the bottom of it.

Any help at all appreciated.

In the dropdown menu at the top right of the queue you can
check and disable the end-of-queue action.

Thanks for the reply shypike. I don't see an end of queue action in there, below is what I see, am I missing something?



For the dropdown menu that says 'on Finish' I have a few of options - Shutdown SABnzbd, Shutdown PC, Standby PC, and Hibernate PC. After that there are my scripts none of which mention end of queue.

Actually ignore me I'm an idiot!

I forgot I was messing and changed the On Finish part from default to blank. default is my default script which probably does nothing when called at the end of the queue, I've since tested it and it seems much better.

Thanks for the help
