Hi all,
I've ran into this issue with my unRAID installation where if I start a download with SABnzbd, say more than 10GB in size, I end up getting either a slow to respond UI or a completely unresponsive GUI (both the unraid GUI and SABnzbd.) The first 10GB or so download with no issue, at full line speed, but then after that, things turn into pretty much a complete dumpster fire. SABnzbd even goes as far as to lose connection.
In the dashboard my, usage looks something like this:
here is htop:
As you can see, I am currently doing transcoding with tdarr, but whether this is running or not does not change the outcome.
As for hardware, currently I'm running a Core i5-4590, 28GB of RAM, a LSI HBA with 6 WD6001F9YZ's (2 Parity), a WD Blue SA510 (500GB Blue SSD) as my cache drive for downloading and docker appdata/docker image, and a Samsung 860 Evo 500GB as a unassigned device, here is my VM disk images.
I've tried tweaking things, I originally started with just downloading direct to HDD, went to an older smaller SSD as a cache, and now this SSD, and its always the same story. I can't imagine I'm bottlenecked by the SSD here, even if I was I wouldn't expect a full stop on network traffic?
I have ordered an i5-12400 as an upgrade due to some unrelated reasons, however this issue was persistent across this current hardware and an older Dell R710. Hopefully I've provided some useful information so I can get this resolved.
Edit: I forgot to mention, I am writing directly to the cache drive, no array logic here.
