Processing message Loop error

[00gxd14g]

{"service_id": "poll_a", "message_id": "771fc879-c5b2-470e-bcf0-6812bc9ee8d0", "message_type": "Poll_Request", "message_version": "urn:taxii.mitre.org:message:xml:1.1", "event": "Processing message", "logger": "opentaxii.taxii.services.poll.PollService", "level": "debug", "timestamp": "2022-10-07T11:43:59.266374Z"}

everything works normally, there is no problem, but when opentaxii is started with gunicorn, "Processing message" loops and this message comes up forever, is there any way to stop this process?
