ComfyUI mantains too many opened connections, causing connection pool depletion

### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

-

### Actual Behavior

-

### Steps to Reproduce

Ran with fresh python 3.12 installation (mamba) and torch 2.8+cu129
Flags --highvr --listen
--disable-all-custom-nodes, ofc
Started 100+ images queue (batch 4)
Eventually webapp freezes
