which reports failure in sabnzbd but if i click retry the rar unpacks without any problem and sends to sickbeard. I have played the files and they are fine.

SABnzbd version: 2.3.2

I'm not sure what I should be checking or how to proceed in troubleshooting this. Need some advice.

Thanks.

Could you enable Debug logging in the Status window and then after it happens again send me the log at Safihre@sabnzbd.org?

sure i just enabled debugging and should have some data for you tomorrow.
Thanks

Please also include the NZB when sending the log.

ok sent.

If there isn't enough info next time I will try getting a log export before i hit retry + nzb and then after hitting retry with nzb and log.

I got your files, but this is a terrible NZB: It's uploaded all in one 5GB file instead of RAR files.
So there is no "unpack" step, all it does is copy it to the final directory when you hit Retry.

Some data was corrupted during transfer, but since there is no PAR2 files it cannot repair anything. So SAB is marking it as failed, since it knows stuff is damaged.
It might still play fine but have some dropped frames here and there, depending on the amount of CRC problems.

I also downloaded the file and received the same CRC errors, so something is just wrong with the original post.

Hmmm, you might have found a bug..
I have to dig deeper.

I can get you more nzb files like this if you need them.

Found it...
Very stupid bug in SAByenc, reaching the limits of what fits in an integer.. Only happens with these crazy posts.
Luckily the decoding still works fine (as you also found), it just falsely gives an error.

Can it be fixed? Happens all the time because i only download 1080 or larger.

Yes it can be fixed, but still these NZB's are pretty bad because they are not split up. So SABnzbd can only assemble the final file from all the mini-parts after all 5GB is done, while with "normal" downloads it can do it for every rar-file.

I just released SABnzbd 2.3.3Beta1 in which it should be fixed!

Which files do I need to keep my settings or when I copy the new files into the directory will it retain them.

Upgrading SABnzbd
For all operating systems, to upgrade SABnzbd simply shut down SABnzbd and re-install. In it's a major release (e.g. from 0.7.20 to 1.1.0), it's always better to finish the queue first before updating.

Thanks.

Your sabnzbd.ini is stored seperate (unless you specify a command line option, but I doubt you do that) from the program files.
So you can safely update the program without affecting your settings.

sent you a logfile and nzb happened again on beta version.

Thanks
