I was trying a reading operation with OdooLocust module on product.template. User was 40 and spawn rate were 1.
After few minute locust rps gets 0
I went to check from UI and saw that server stopped responding. The server was running on a linux vm with docker environment but the database was in AWS.
I restarted the docker with docker compose but next what I see was like this
```

I suspect this is something with postgres. Is there any workaround for this.
Any help is appreciated.
