Downloads Failing to Complete

[wintermute]

Version: 2.1.0RC1 [1968584]
OS: Ubuntu 16.04.2 LTS
Install-type: linux repository
Skin (if applicable): (Ex: Default, Plush, Smpl)
Firewall Software: none
Are you using IPV6? no
Is the issue reproducible? yes

For whatever reason I'm not able to complete downloads for one of two reasons:

1) The job stops downloading at 98% or 100% and stays stuck in the queue.
2) The job finishes downloading, starts to unpack and everything freezes.

I hadn't had problems in quite a while with this set up and nothing had changed.

I have tried updating linux and sabnzbd.
I've also tried restarting sab, deleting everything in the incomplete folder, and trying again.

I'm not sure what the cause is here, I'm hoping someone smarter than I can assist.

Thank you in advance.

I've also tried completely uninstalling sab, wiping out the sab directory in my home directory, and starting over to no avail.

Can you turn on Debug logging in the Status window? And then when it happens again, get the log by clicking Show Logging in the Status window?
This will include an anonymized copy of your settings so we know what is going on.
If you share it here or send it to [email protected] we can take a look at it!

Here is a log taken after the server has been running for several hours with the same download stuck unpacking.
