Investigating worker subrequest

Hello, According to the sub-request graph on my dashboard, it appears some of my workers are triggering a high amount of sub-request. For reference, I have a steady 5 worker invocations / s, each of them should be doing 1-3 sub-request. The request graph is completely flat but my sub-request graph shows high peaks. I'm trying to trace back if a particular payload is responsible for these anomalies to find a fix, but I'm not sure how I can identify which job execution is responsible for all the unexpected sub-requests. From my understanding the available logs do not give an executed sub-request number. If you have any ideas how to approach this issue it would be of great help, thank you 🙏
