+> Q: I see GPU OOM or "free memory is less than desired GPU memory utilization" errors. How can I fix it?
+
+A: Refer to [GPU memory calculation and configuration](../configuration/gpu_memory_utilization.md) for guidance on tuning `gpu_memory_utilization` and related settings.

 > Q: I encounter some bugs or CI problems, which is urgent. How can I solve it?
 
 A: At first, you can check current [issues](https://github.com/vllm-project/vllm-omni/issues) to find possible solutions. If none of these satisfy your demand and it is urgent, please find these [volunteers](https://docs.vllm.ai/projects/vllm-omni/en/latest/community/volunteers/) for help.
