Pattern

Request Backpressure Missing

stream-accepts-after-limit

A recurring streaming-control issue where the system accepts or continues processing data after an explicit limit or completion signal, wasting server resources; fixes typically enforce “stop reading/close/abort” and consistent async lifecycle handling.

Zustand persist middleware does not write during the test setup

java.lang.NoSuchMethodError: org.springframework.http.server.reactive.ServerHttpResponse.getRawStatusCode()Ljava/lang/Integer;. Outcome: at io.sentry.spring.webflux.SentryWebFilter.finishTransaction(SentryWebFilter.java:149).

such as the entry of a wrong password or wrong CSRF tokens. Tension: more an user error than a system error or caused by spam bots. Outcome: collect exception classes which are safe to ignore.

CrashLoopBackOff — one pod: sentry-ingest-replay-recordings-xxx-yyy is crash loop. Tension: Broker: Unknown topic or partition. Outcome: After last upgrade to chart sentry-18.0.0, app version 23.3.1.

Failed to report an error on a session because there is none active. — on the Application Output. Tension: I see the manually captured error on my Sentry Dashboard. However I'm concerned about these warning messages.

background task blocks eventloop — reload = True or workers > 1. Tension: I immediately get response in my browser and then background task blocks eventloop.

the background job never runs — my `BackgroundTasks` only execute when declared inside an async dependency. Tension: No exception is raised, the route returns normally. Outcome: If I move the `bg.add_task()` call into the route itself, it works as expected.

Whisper transcription is not produced continuously from websocket audio chunks

some events are asynchronous and not come from a frontend request.

it waits for stream_results to finish and then returns response like that instead of gradual streaming result — return StreamingResponse(stream_results(), media_type='application/x-ndjson'). Tension: print works as expected and outputs the result as it is generated. But yield does not. Outcome: What am I doing wrong?

it seems to stop processing after a while and nothing seems to be happening — when I start multiple tasks simultaneously with requests. Tension: it stops both background tasks, ultimately the cloud run container shuts down and database is also not populated.

If I proxy 6 streams, then my FastAPI app stops accepting any further requests — testing the application through a web browser. Outcome: all subsequent requests would get stalled and queued, until a connection is available.

Waiting for background tasks to complete. — Whenever I gracefully shut down my FastAPI app by saving a file (with the `--reload` option). Tension: "Shutting down sessions" is never logged because it is waiting for all background tasks to be completed, which will never happen. Outcome: How am I supposed to close my sessions so that FastAPI can properly shut down?

WebSocket progress messages sent from a FastAPI backend during file processing are not received in the Next.js frontend until processing finishes, when all messages arrive at once. Backend logs show progress updates are generated successfully.

send each chunk of the streamed response directly as it is received — using `httpx` and FastAPI to stream HTTP response chunks directly from an upstream server to a client. Tension: instead of buffering all data and sending it at the end. Outcome: So wrapping the entire `httpx.AsnyncClient()` in the async function `stream_response()` and yielding from there.

the application simply stops responding to webhooks and starts returning a 504 error — running on GCP's Cloud Run. Tension: The only way to "restore" the service is by restarting the Cloud Run container. Outcome: The last message is "Instantiating PubSub client...", then the POD stucks.

Error: read ECONNRESET — POST request in postman that recieves an audio file, and 2 params. Outcome: "There was an error parsing the body".

the processing of the webhook event payload to fail once (or more) — handling Stripe webhooks. Tension: wait some time during which the organization gets created, and then retry the operation. Outcome: this would allow for the processing of the webhook event payload to fail once (or more), wait some time during which the organization gets created, and then retry the operation.

Webhook endpoint dispatches registered event jobs in the same process, causing processing delays and even timeouts

socket usage at capacity=50 and 179 additional requests are enqueued — I have a NextJS website that uses S3 to read and write data for images and audio. Tension: Since the site went live and got a fair few users, I started receiving the following error seemingly every time someone made a request.

I also did not find another http library, that supports canceling get requests in progress. Tension: Did I miss a python http library that supports canceling?

aws s3 sync and aws s3 cp fail with MissingContentLength / stream is not seekable errors

facing throttling issues (503 errors) — writing to S3, and facing throttling issues (503 errors). Tension: our ingestion service still encounters 503 errors. Outcome: the files are showing right under my bucket at the root level.

Timeout waiting for connection from pool. Tension: Task 4217 in stage 4.0 failed 4 times. Outcome: Job aborted due to stage failure.

Minio upload with a stream blocks until the file stream is closed

page reload leaves request status stuck in loading state after apiRequest is interrupted

I want Postgres to clean up properly in case of improper client termination — each client can create its own subscriptions via listen + notify + triggers. Outcome: How can I accomplish this?

strcpy(overflowing, overflowingtext) does not reliably overflow into p1

Buffer overflow cannot be demonstrated reliably

HTTP request keeps accepting data after the size limit is exceeded, wasting server resources
