SABnzbd Forums

I've always used "abort if cannot be completed" and believed sab when it said something could not be completed.

yesterday having failed to download something around 100 days old I thought I'd try "NZB completion checker" on various versions of the thing I wanted to see just which one was available. It told me they all were, including the one sab had said wouldn't complete. I turned off "abort if..." and sab downloaded the item fine (with a small repair).

I turned on "check before download" and sab says (of the thing it's already happily downloaded)

Download might fail, only 63.1% of required 100.2% available

any ideas?

None, except that the server may be doing odd things.
Can you email one or more example NZBs to bugs@sabnzbd.org ?
Please the URL of this message and the Usenet provider you are using.

Got your NZB files.
These are rather nasty NZB files.
They contain a bunch of duplicate segments.
Meaning that the NZB has more than one (non-matching) candidate for a specific part of a file.
This is a serious error by the Usenet indexer where you got the NZB from.
You're lucky that they download at all, because SABnzbd needs to pick one candidate for such cases.
It just happens to pick the right one.

Having said that, there is an actual bug in SABnzbd.
It needs to discard one of the candidates and it will not download that candidate.
However, it does add the duplicate candidate to the total amount to be downloaded.
And that is the reason that the download is aborted.
It thinks it needs 1G, while only 500M is needed!

I'll fix this bug in the next release, but that will not solve the underlying problem of bad NZB files.

Thanks :-)

I'm wanting to switch to Sonarr from Sickbeard but it insists on having "check before download" disabled. Does this do anything or not? I have a quotad internet connection with limits and I hate to download things which may fail.
I still get some through sickbeard, even with it ticked but not many.

It's better to replace it with "abort if cannot completed".
Much more reliable for posts that have many missing articles.
