Any ideas?

 

This a brand new system with new disks and not running any dockers with 4GB.

 

This box is currently being restored from backup because my other UnRaid box became unstable after 24 hours because Reiser.

Not too happy with Unraid right now.

How much RAM to you have set aside for the APU's Radeon integrated graphics? Try setting it in the BIOS to the lowest possible value. Of your 4096 MB of RAM there's only 3388 MB available to unRAID.

Thanks John! Did not think about that.

 

However, should just plain unraid with no dockers and just minimal plugins require > 3GB memory?

 

I got away with 2 GB on my old system with more disks...

 

 

I don't know what version of unRAID your old server ran but version 6 needs more RAM than version 5. I think 4 GB ought to be enough for a basic NAS but 3.3 GB is a little tight, as you've seen! See how you get on once you've freed up some more RAM and if necessary add another 4 GB stick. It's not that expensive.

 

Have you tried running in safe mode (without plugins)?

Have not tried safe mode.

 

I have turned off all plugins except Dynamix webGui.

 

More memory really means at least 16GB (why go with 8GB if ~4GB is an issue on the absolutely barest system). Also, I would want to run memtest for at least 24 hours on it. It's not the costs at all, but I'm about 60 hours into troubleshooting these two issues and I just want to get a stable system.

 

Again, thanks for you guys taking a look at this!

 

 

 

Found some slower dimms to get to 8GB.

 

Will see how that does.

 

If ~4GB is not enough for my set up of 10 disks with no dockers, I would think the suggest that the wiki be updated n'est pas?

"For most unRAID builds, 2GB of RAM is more than adequate. If the server will be used for tasks such as running torrents or virtual machines, at least 4 GBs of RAM is recommended."

Sure, no dockers, but you are running a bunch of plugins...

 

In this case my primary suspect would be cache dirs. Do you still get OOM after a reboot with that one removed?

Moving to 8GB seems to have solved it.

 

Thanks!
