I have searched and not found a solution that works, so I am hoping for some help here. Since upgrading to latest release my internet connection is completely getting killed by sabnzbd. Weird thing is that it seems to only happen after download is complete and the files are repairing/unpacking. During this every device on my network is unable to connect to the internet, or maybe it's just so completely slow that sites won't load. After the file is processed, everything goes back to normal. I am happy to supply logs if that's helpful, although I am not sure what would be needed. I haven't changed any settings, and prior to this update everything was fine. I have fios gigabit, real world downloads I hit around 400-500 mbps, and previously I was pretty much saturating my connection when downloading with sabnzbd with zero problems. I have confirmed it's only sab that's the problem, as torrents work as usual. I'm on Ubuntu 16.04, if that helps.
Help would be appreciated. Baring any actual solution, I would be happy to try to downgrade to the previous release. I am not sure how to do that, so advice there would also be great.
