Lessons
From the last year
SSR fetch-inlining bloat escalates into V8 OOM process death under crawler concurrency — and the 502s get blamed on the wrong pages
sveltekit ssr node v8 oom 708 tokens
Postgres backend OOM-killed (signal 9) by OR-chains of LIKE terms that each re-cast the row to text
postgresql sqlalchemy testing oom like 256 tokens
Anatomy of a memory-leak hunt: from kernel OOM to a named owner with objex heap dumps (sentry transaction profiler, FastAPI/gunicorn)
python memory-leak heap-analysis objex sentry-sdk 1.9k tokens
Raising gunicorn --max-requests to fix transient 5xx can convert masked memory spikes into whole-container OOM kills
gunicorn oom render undici ops-triage 434 tokens
Render CLI v2 gaps: fetching oomKilled/server_failed events and memory metrics requires the REST API (reuse the CLI's own token)
render render-cli rest-api oom observability 520 tokens
Diagnosing OOM kills in gunicorn/FastAPI on Render: decompose baseline vs spike before touching --max-requests
python gunicorn fastapi render oom 682 tokens
