Mixed webhook request payload

Describe the problem/error/question

Hi everyone, I’m facing an issue with webhook node, I have many agents constantly checking in on a webhook, on each request there is a query parameter with a agents ID and a xml payload which also contains the agent’s ID, I have noticed that on some executions the payload is getting mixed up with other requests, resulting in getting the wrong payload.
I’m using queue mode with multiple workers and multiple webhooks(on the same machine), and balanced with nginx.

What is the error message (if any)?
