### Search before asking - [X] I had searched in the [issues](https://github.com/apache/skywalking/issues?q=is%3Aissue) and found no similar issues. ### Apache SkyWalking Component Python Agent (apache/skywalking-python) ### What happened I started my tornado service and sent two identical requests, but only one link?  ### What you expected to happen There is a problem with the link ### How to reproduce There is my code. tornado==6.1 `import asyncio from skywalking import agent, config from tornado.web import Application, RequestHandler, url from tornado.httpserver import HTTPServer from tornado.ioloop import IOLoop class SwTornadoHandler(RequestHandler): async def get(self): await asyncio.sleep(0.4) self.write({"ok": 1}) if __name__ == '__main__': app = Application([ url(r"/api/web/test", SwTornadoHandler) ]) http_server = HTTPServer(app, xheaders=True) http_server.bind(9696) http_server.start(2) config.init( protocol="http", service_instance=f"127.0.0.1:9696", collector_address="127.0.0.1:12800", service_name="python-api-service") config.disable_plugins = ["sw_falcon", "sw_psycopg2", "sw_pyramid", "sw_sanic"] agent.start() IOLoop.current().start() ` ### Anything else In skywalking/trace/context.py . I modified the code and found it normal, but I don't know why. source code: ` def _spans_dup(): spans = __spans.get()[:] __spans.set(spans) return spans` modified code: ` def _spans_dup(): # spans = __spans.get()[:] # __spans.set(spans) # # return spans return __spans.get() ` ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
