Cannot receive WebSocket messages.

### 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

WebSocket messages can be received continuously until the task is completed.

### Actual Behavior

The service starts normally, but after running for some time (possibly more than 10 hours, the time is random), it becomes unable to receive WebSocket messages. The symptom is that initially, a WebSocket message is received: `{"type": "status", "data": {"status": {"exec_info": {"queue_remaining": 0}}, "sid": "2d72ff08-c7b6-4792-ac4f-a4d8d95308ef"}}`, and then it remains unchanged, causing the polling to get stuck. I am using ComfyUI version 0.3.43.

### Steps to Reproduce

just run for a long time

### Debug Logs

```powershell
{"type": "status", "data": {"status": {"exec_info": {"queue_remaining": 0}}, "sid": "2d72ff08-c7b6-4792-ac4f-a4d8d95308ef"}}
```
