Plex with GPU crashes server

[Psyonus]

Hi Guys,

 

So I have had a great deal of instability of late and have tried a number of things including swapping out memory for known working memory and removing all plugins and dockers and starting fresh.

I installed a clean instance of plex with my GTX 1660 Super allocated to it for transcoding then redownloaded all the metadata, I was able to start and stop the container without issue.

I have found however if I play a single file that utilizes the gpu (any transcoding) when I go to close that container the entire server locks up and must be hard reset.

My only option it seems is to run plex with no hardware transcoding... the same issue I have found in passing a GPU (historically) to a VM, when I shut that VM down the server freezes.

To be clear I am not running a VM at the moment and the VM service is disabled.

 

It is a real shame because I loved unraid and used it for many years but after 2 months of constant crashing and instability other than abandoning unraid and buying a synology that can use hardware transoding can anyone offer any ideas as to why this is happening? I don't even care if the reason fixes the issue I would just like to understand why this is crashing reliably everytime.

I followed spaceinvaderone's tutorial for Nvidia GPU passthrough to the letter and have no other dockers or VM or plugins installed.

 

As the entire server is frozen up I can't get a log to attach.

First thing would be to run MemTest from the boot menu for at least 24 hours. When it crashes do error messages appear on the console or does it just freeze?

Hey mate,

So I have run memtest on this ram with no errors, I have also used this ram for 3 years with no errors.

Could it be due to the GPU like it is in VM passthrough?

 

Thanks for the suggestion
