Thanks for your reply JorgeB. I've read this as well. I think you are almost certainly correct, and it's just a coincidence that i always see 25% RAM usage. Still, it seem so odd to me that it is using exactly that much so consistently. I guess I wonder, is there any way to run an application that would say, just use 6GiB of RAM? It would assuage my concerns haha. There must be some program like this I could find, do you have any idea? I will look for one and post if I find one.

Thank you for replying to the old post!! You saved me a lot of pain. I ran into the same, unfathomably useless error message. Nothing in the main server logs. The app/docker that faild had errors in the logs had, wish I took a screenshot but they said something about "window management" IIRC. Could be wrong on that. Regardless, couldn't find anything that mentioned port conflicts - and ultimately that was my issue as well. Changed the port in the docker and all is well. If you see this error, check your port settings for conflicts! If you are part of Unraid team, please try to detect this and give a more verbose error (and/or help docker image creators do the same).

Hi there! I have recently upgraded my RAM, and I don't think it is being utilized fully. System details: UNRAID OS Version: 6.11.5 RAM: 16GB (previously 4GB) I have been using this box for ~6 months. I noticed my RAM was always full, and some docker apps were periodically crashing. When I looked at the logs, I saw out of memory errors, so I bought and installed more RAM. While my dashboard now shows 16GiB of RAM after the upgrader, it also always shows utilization pinged at 25% - the same amount of RAM as was previously installed. When I run "free -h" I get this output: total used free shared buff/cache available Mem: 15Gi 2.5Gi 274Mi 1.0Gi 12Gi 11Gi Swap: 0B 0B 0B Not sure if this copy/paste will format correctly, but basically, it seems that only 4GiB is allocated to be used as RAM and shared VRAM, with 12GiB allocated to buff/cache. Side note, I assume this is in my BIOS, but I don't even use the intel integrated graphics, its headless, so I should probably reduce the shared RAM to minimum. My limited research seems to imply that there is a linux kernel setting to change these allocations. I haven't been able to find out how to tweak this, and wonder if BIOS settings come into play, aside from the VRAM. I did not update my BIOS settings after installing the new RAM. 1) Is there any way to change the allocation to "buff/cache"? 2) Is this normal and I'm just being a ding dong? 3) Is there a way to 'stress test' the RAM usage - ie run a docker that uses 8GiB of RAM, and see if the kernel allocates the RAM to this process? Thanks all!
