KoboldCpp seemingly hanging/freezing PC when processing image sometimes

[DarkPulse]

Describe the Issue
Recently I've gotten into making use of an mmproj for a Qwen 3.5 finetune I run. I had no problems with image analysis before, but once I updated KoboldCPP to 118.1, I have gotten two system hangs and one outright system crash while attempting to have it analyze an image. If it freezes, the entire system locks, forcing a hard reset.

It doesn't do that all the time with every image, but it does that some of the time, and there seems to be no pattern to what triggers it. I have had no issues before now with it and my system is usually rock solid (weeks of uptime), so something tells me something went buggy with the latest update in a way it did not like. I'm going to try rolling back to the previous version to see if it continues there and will report back.

It's definitely not running out of RAM either - I've got a GeForce 4080 Super, the quant I have leaves about 1 GB of VRAM free, and I'm actually offloading image processing onto the CPU to maximize token generation speed. Main PC itself has 64 GB of RAM.

Additional Information:
Win11, Ryzen 5900X, GeForce 4080 Super, KoboldCpp 118.1. Seemed to not happen on 117.1.

Update: This is happening in 117.1 as well, just had a crash on that when I rolled back, analyzed a few images, and eventually while it was doing one, it reset the system. At this point I'm not sure if it's something with KoboldCpp, or if there is something very weird on my system wigging out, but it is ONLY when I'm having it analyze the images that it ever bombs out like this.

I'll try putting it on the GPU next time to see if that can narrow something down more. Never had an issue doing it on the CPU until when I filed this report.

Cool, maybe try adjusting the thread count and seeing if it runs out of RAM too.
