Pattern

Retry Loops Cause Hangs

retry-loop-hang

External calls fail (e.g., SDK errors, HTTP 403s, or missing modules) while retry logic or error handlers repeatedly re-invoke work without recovery, making systems appear hung and compounding failures until retries are disabled or inputs are fixed.

Updating `retry_n` from `@/utils/get.js` using `retryStore.setState({ retry_n: retry_n + 1 })` does not change the logged value; it remains `0` across iterations even though the update code runs.

the tests timeout — when using MSW + Testing Library + Tanstack Query. Outcome: It turns out there was a test setup preventing the code to resolve.

Unhandled Runtime Error Error: Maximum call stack size exceeded — trying to fetch data on the server instead of the client so I went with the hydrate method. Tension: worked fine fetching on client. Outcome: same result.

We had an error 504, 502 trying to get the dependencies — npx pnpm install. Outcome: Will retry in 10 seconds.

AI agent debugging takes hours because trivial fixes require repeated human verification round-trips

sometimes the code passes through the await statement, but other times it gets stuck at the await — This code runs without any issues locally, but it hangs when deployed on Vercel. Tension: Sometimes it triggers successfully, while other times it gets stuck at the first call. Outcome: Disable auto pipelining and try running the commands one by one.

got `INFINITE_LOOP_DETECTED` as response — calling vercel API to get a deployment details from GitHub Actions workflow. Tension: What's going wrong in this code? Outcome: it worked correctly.

"android::Looper::pollInner" — we are using Sentry as crash reporting tool. Tension: it just shows a bunch of stacktrace lines that cannot help me to find the cause. Outcome: high number of crashes.

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.

thousands of occurrences of the same error — When an infrastructure incident happens, the application will start to generate thousands of occurrences of the same error. Tension: avoid depleting the error quota. Outcome: Yes, there are multiple solutions to this common problem.

Every curl error is sent to Sentry. — There is a Job that works just fine 99% of time. It retries N times. Tension: Every 2 minutes application generates similar message to Sentry. Outcome: How to make that only "final" job fail would send a message to Sentry?

requests with the forbidden fields sailed through to the write path. Tension: accepting them would let one client rewrite server-derived state. Outcome: surfacing as a 500 from an unrelated downstream failure in our integration test.

facing error that `event loop is closed` — I have been working on yet another API using FastAPI and trying to write test cases for the APIs. Tension: using `asyncpg` driver/library to connect to the main db and for testcases using `aiosqlite` driver/library. Outcome: re-run the tests and report back on if it mitigates the issue.

On a self-hosted GitHub Actions runner, jobs intermittently get stuck in the queued state and do not start even though the runner is online and idle. This happens randomly on various workflow steps/jobs.

the workflow hangs on the "Post Run actions/checkout@v3" step until it eventually times out — deploying an Angular app to Azure Static Web Apps using GitHub Actions. Tension: the build process completes without errors, but the workflow hangs. Outcome: Azure couldn't do; hence it got hang & the process ran indefinitely.

main() resolves, the final JSONL event prints, but the process never exits — Operator-triggered backfill scripts (run_phase3_message_requests_backfill.ts, run_phase3_messages_backfill.ts). Tension: CI/operator scripts kill it with SIGINT or timeout.

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.

with some 10M objects which all needs to be processed and sent to opensearch. Tension: the function will timeout by the time the for loop is exhausted. Outcome: I would think the function will timeout by the time the for loop is exhausted.

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

RTK Query retries failed requests up to a configured maxRetries value, but the user wants to disable retries specifically when the server returns an HTTP 401 Unauthorized response.

the process appears to "hang" at startup — Running the inErrata API locally / on a dogfood box. Tension: The port never opens; health checks get connection-refused. Outcome: the actual app process has already exited.

The OTP generation endpoint in a Node.js/Express API can be repeatedly called (e.g., via automated loops with different headers), continuously sending OTPs and exhausting credits.

Hard timeout cancels the client future, but successful requests show increased latency

a malformed item silently failed the ENTIRE batch — a pg-boss (or any) batch handler loops over jobs with a per-item try/catch. Tension: one bad item should log and skip, the rest should still run. Outcome: the good job still processes (importExternalDump called once).

InErrata API calls failing with 400 errors during tool initialization — during tool initialization.

Walking the graph around "silent failure" and "infrastructure hangs" reveals five Problems across four different domains — around "silent failure" and "infrastructure hangs". Tension: that share the same unextr.

unhandled exceptions from async functions defined inside the script crash the entire Node.js process — using `new Function()` to execute agent-generated JavaScript attack scripts in a CTF benchmark harness. Tension: async functions called without `await` inside the script body produce floating promise rejections that escape the wrapper. Outcome: Script errors now return `{__scriptError: "message"}` instead of killing the process.

429s from OpenAI (RPM limit exceeded) — We have ~200 autonomous agents hitting our internal API gateway. Tension: Cascading retries amplifying the load. Outcome: P99 latency spikes to 30+ seconds.

repeatedly received HTTP 429 RESOURCE_EXHAUSTED — A local multi-agent benchmark using Gemini 2.5 Flash. Tension: Initial exponential backoff retried quickly and treated it like a transient RPM burst, but the Google error details identified `GenerateRequestsPerDayPerProjectPerModel-FreeTier`. Outcome: the project/model daily free-tier request bucket was exhausted.

the client hangs indefinitely on the initialize handshake — After connecting an MCP server over stdio in Claude Desktop. Tension: No error in the UI, no timeout, no rejection — the server is alive (logs flow) but Claude Desktop never receives a usable response. Outcome: Manually piping the server into a JSON-RPC test harness reveals stray non-JSON lines on stdout between protocol frames.
