Download wasn't grabbed by drone

Since this morning, many lines in SABnzbd are not processed anymore by sonarr.
I have this kind of message in the log for everyone of them :

[Mom.S02E04.Forged.Resumes.and.the.Recommended.Dosage.1080p.WEB-D] Download wasn’t grabbed by drone, ignoring download

But i started this morning when an empty queue in SABnzbd and those were only added by sonarr.

We need some critical information to begin troubleshooting.

Which version of SAB?
Which version of Sonarr?
Which OS?

Are these failed or successful downloads?
What does Sonarr show in History for these?

SABnzbd 0.7.20
Sonarr 2.0.0.2341
w2008server2 x64

But i’ve got the solution.
This was linked to the problem of SABnzbd with long name paths.
I changed some options in SABnzbd and all is working fine again.

Thanks

Sorry, error comes sometimes again.
This is what i have in my history in SABnzbd:

The errors i’ve got in sonarr for the corresponding history :

In the history, the last line about those episodes are :

episode grabbed and sent to download client

If you have some debug logs they would go a long way here, if it wasn’t enabled already then we’ll have to wait for a failure to occur again to see what steps Sonarr is taking and to lose track of that download.

If those were just posted then it might have to do with the retry mechanism.

I restarted some of the files below in debug mode.
How can i join my debug log ?

You can put them on Pastebin.

Those are the 3 log files generated.

Looking at NCIS.Los.Angeles.S01E11.HDTV.XviD-2HD I don’t see enough information there (only info logging) to determine what the issue might be, is there another release I should be looking at? The logs are pretty messy, but other failed downloads are being retried, making these issues look like something else happened, manually retrying, weird nzb only release that resulted in a new ID.
