SpaceInvaders GPU Transcoding Benchmark container causing massive server hangs

Featured Replies

Apologies but posting this here because no one ever responds to container specific threads anymore. I guess AI has most of the answers.

Have twice tried to use this container to run a test for number of x265 to x264 transcodes my i7-7700 iGPU can handle. Using the default test clips included. The test runs without issue until the CPU appears to hit its limit of simultaneous streams (4). At that point everything hangs, and I mean everything. The test stops working and can't be stopped, no pages on the Unraid GUI will load nor will any other containers GUI. I am also unable to SSH in to the terminal. I can't access my shares on the local network. It's a full blown hang.

Have been able to enact a graceful shutdown via a quick push of the physical power button on the server, but otherwise would have been looking at a hard shutdown.themagiceye-diagnostics-20260902-1243.zip

Given that @SpaceInvaderOne now works for UnRaid directly, perhaps consider more extensive testing from him or the team before publishing containers to the app store and videos to YT. This one is a great idea, but seems there might be some real issues for some with the implementation.

Here are the container logs I grabbed after the reboot, and have attached diagnostics as well. Hope it helps to find the issue.
