Downloads keep dropping to 0, log shows "Delayed"

[Johnster]

I'm running SabNZBD on Linux Mint 21.3 Cinnamon. It's been generally working well for a few years until recently. The problem is that downloading will start out well, but drop off until it eventually it stops at 0b\s. And there it sits until eventually it starts up again. Occasionally when this happens the console will lose connection and need to be reconnected. It happened again today so I started looking through the logs. I found a pile of entries like this:

In this case it started working again at about the 421 second mark, but 7 minutes of inactivity is very frustrating. I have the cache set to 2G and it sits on a local SSD so it shouldn't have a problem there. Anyone have any idea where I should look to fix this?

The problem is an IO lockup. Something is not allowing us to write caste enough to disk.
Is there another disk you could have your Download folder on?

The completed download folder is on a mounted NAS share, the temp folder is on a local SSD. Could it be the NAS share is preventing the write?

Try it on the local disk using the 10GB test download.
