Warning: ComfyUI v0.31.0 Causes Random Crashes and CUDA OOM Errors
ShutUpYoureWrong_ · reddit · 2026-08-08
Reddit users are reporting severe stability issues after updating to ComfyUI v0.31.0. When generating with the H3 model, users are experiencing random crashes, CUDA errors, and Out of Memory (OOM) issues that didn't occur previously.
The author noted that they changed nothing except updating from v0.30.0. To isolate the issue, they performed a fresh install of v0.31.0, which still resulted in constant crashes, confirming a critical bug in the new version itself. Users are advised to hold off on updating for now.
