Hi all recently update all my ETLs to run in prefect 2.0 but now I am getting a problem with the agent crashing. I am not sure if it matters but I am running the agent in a virtual environment here are the error messages that I am getting Traceback (most recent call last): File "c:\etls2\lib\site-packages\prefect\utilities\services.py", line 46, in critical_service_loop await workload() File "c:\etls2\lib\site-packages\prefect\agent.py", line 194, in get_and_submit_flow_runs responses = await self.client.get_scheduled_flow_runs_for_work_pool( File "c:\etls2\lib\site-packages\prefect\client\orchestration.py", line 2282, in get_scheduled_flow_runs_for_work_pool response = await self._client.post( File "c:\etls2\lib\site-packages\httpx\_client.py", line 1845, in post return await self.request( File "c:\etls2\lib\site-packages\httpx\_client.py", line 1530, in request return await self.send(request, auth=auth, follow_redirects=follow_redirects) File "c:\etls2\lib\site-packages\prefect\client\base.py", line 249, in send response = await self._send_with_retry( File "c:\etls2\lib\site-packages\prefect\client\base.py", line 192, in _send_with_retry response = await request() File "c:\etls2\lib\site-packages\httpx\_client.py", line 1617, in send response = await self._send_handling_auth( File "c:\etls2\lib\site-packages\httpx\_client.py", line 1645, in _send_handling_auth response = await self._send_handling_redirects( File "c:\etls2\lib\site-packages\httpx\_client.py", line 1682, in _send_handling_redirects response = await self._send_single_request(request) File "c:\etls2\lib\site-packages\httpx\_client.py", line 1719, in _send_single_request response = await transport.handle_async_request(request) File "c:\etls2\lib\site-packages\httpx\_transports\default.py", line 352, in handle_async_request with map_httpcore_exceptions(): File "C:\Program Files\Python310\lib\contextlib.py", line 153, in exit self.gen.throw(typ, value, traceback) File "c:\etls2\lib\site-packages\httpx\_transports\default.py", line 77, in map_httpcore_exceptions raise mapped_exc(message) from exc httpx.RemoteProtocolError: <ConnectionTerminated error_code:ErrorCodes.NO_ERROR, last_stream_id:235, additional_data:73657373696f6e5f74696d65645f6f7574> Traceback (most recent call last): File "c:\etls2\lib\site-packages\prefect\cli\_utilities.py", line 41, in wrapper return fn(*args, **kwargs) File "c:\etls2\lib\site-packages\prefect\utilities\asyncutils.py", line 260, in coroutine_wrapper return call() File "c:\etls2\lib\site-packages\prefect\_internal\concurrency\calls.py", line 245, in call return self.result() File "c:\etls2\lib\site-packages\prefect\_internal\concurrency\calls.py", line 173, in result return self.future.result(timeout=timeout) File "C:\Program Files\Python310\lib\concurrent\futures\_base.py", line 439, in result return self.__get_result() File "C:\Program Files\Python310\lib\concurrent\futures\_base.py", line 391, in __get_result raise self._exception File "c:\etls2\lib\site-packages\prefect\_internal\concurrency\calls.py", line 218, in _run_async result = await coro File "c:\etls2\lib\site-packages\prefect\cli\agent.py", line 189, in start async with anyio.create_task_group() as tg: File "c:\etls2\lib\site-packages\anyio\_backends\_asyncio.py", line 662, in aexit raise exceptions[0] File "c:\etls2\lib\site-packages\prefect\utilities\services.py", line 104, in critical_service_loop raise RuntimeError("Service exceeded error threshold.")

Hey Tabari, thanks for reporting this. Is the agent able to run any flows at all? Or does it immediately crash?

Hi Bianca it runs flows for awhile then it crashes

Hmm..if it's a linux vm, i'd recommend checking out this guide on how to set up the agent as a systemd service

It's windows.

Ah, it seems as though another user reported a similar error. As a first step for troubleshooting, could you Alex's recommendation?

Thaks I will try this!
