## Conversation Summary

|
|
user: A new session was started via /new or /reset. Run your Session Startup sequence - read the required files before responding to the user. Then greet the user in your configured persona, if one is provided. Be yourself - use your defined voice, mannerisms, and mood. Keep it to 1-3 sentences and ask what they want to do. If the runtime model differs from default_model in the system prompt, mention the default model. Do not mention internal steps, files, tools, or reasoning.

httpx.ReadTimeout
|
|
root@inference-api-57cffd9545-54k2t:/app#
|
|
```
|
|
assistant: Classic — `httpx.ReadTimeout` on line 163 (non-streaming path) with zero error handling, so it just barfs a full traceback into the logs instead of returning a clean 504. Same issue would hit the streaming path's initial connection too.
|
|
|
|
The fix: wrap both httpx calls in try/except for timeout/connection errors and return proper JSON error responses instead of letting FastAPI puke stack traces. I'll also bump the timeout a bit for good measure.
|
|
assistant: Also need to handle timeouts in the passthrough route:
|
|
assistant: Quick sanity check:
|
|
assistant: Here's what I changed:
|
|
|
|
1. **Caught `httpx.ReadTimeout` and `httpx.ConnectTimeout`** on the non-streaming path (line 163 area) — returns a clean `504` with a JSON error body instead of a full traceback vomit in the logs
|
|
2. **Caught `httpx.ConnectError`** too — returns `502`
|
|
3. **Streaming path** already had a try/except but now uses the same timeout constant
|
|
4. **Passthrough route** got the same treatment
|
|
5. **Bumped timeout from 300s → 600s** — some models are just slow, 5 minutes wasn't cutting it
|
|
|
|
The root cause is that the upstream vLLM/sglang backend is taking longer than 300s to respond on some requests. The timeout itself might still happen (slow model, queue backlog, whatever), but now instead of 50 lines of traceback spam you get a single-line `⚠ Upstream read timeout` log entry and the client gets a proper `504` response.

[Tue 2026-05-05 06:32 UTC] while we're in here. How many simultaneous requests can fastapi handle? DOn't know if there's a limit per worker
|
|
assistant: By default, `uvicorn.run()` with no workers arg starts **1 process, 1 event loop** — but since it's async, it can handle many concurrent requests on that single loop. The bottleneck isn't FastAPI itself, it's the **httpx.AsyncClient** usage pattern.
|
|
|
|
Looking at your code — you're creating a **new `AsyncClient` per request**:
|
|
|
|
```python
|
|
async with httpx.AsyncClient(timeout=...) as c:
|
|
r = await c.post(...)
|
|
```
|
|
|
|
Each `AsyncClient` creates its own connection pool. So there's **no connection reuse** between requests — every request opens a fresh TCP connection to upstream. That's wasteful but doesn't cap concurrency.
|
|
|
|
The real limits:
|
|
|
|
- **No worker limit** — you're running single-worker. One process, one uvicorn event loop. That's fine for async I/O-bound work; the loop can juggle thousands of coroutines.
|
|
- **No connection pool limit** — since you spin up a new client each time, each one defaults to `max_connections=100`, `max_keepalive_connections=20`. But since they're ephemeral, it's effectively unlimited (and messy).
|
|
- **uvicorn `--workers`** — not set, so 1 worker. If you wanted multi-process parallelism, you'd pass `workers=N` to `uvicorn.run()` or the CLI.
|
|
|
|
**The move:** Create a shared `AsyncClient` at app startup with tuned pool limits. Way more efficient, and lets you control concurrency explicitly. Want me to refactor to use an app-lifespan client? Something like:
|
|
|
|
```python
|
|
@asynccontextmanager
|
|
async def lifespan(app: FastAPI):
|
|
app.state.client = httpx.AsyncClient(
|
|
timeout=600.0,
|
|
limits=httpx.Limits(max_connections=200, max_keepalive_connections=50),
|
|
)
|
|
yield
|
|
await app.state.client.aclose()
|
|
```
|
|
|
|
Then all routes use `request.app.state.client` — connection reuse, proper pooling, no per-request overhead. And you can tune `max_connections` if you need a ceiling.
|
|
|
|
Want me to make that refactor?

[Tue 2026-05-05 06:33 UTC] Well I spin it up via supervisor. the config is `normalizer_proxy.conf`
|
|
assistant: There it is — `--workers 1`. So you've got a single uvicorn process handling everything.
|
|
|
|
Couple thoughts:
|
|
|
|
- **For your workload (pure async I/O proxy), 1 worker is probably fine.** The event loop can juggle hundreds of concurrent upstream requests without breaking a sweat. You're not doing CPU-bound work — just shuttling JSON around.
|
|
- **Bumping to 2-4 workers** would give you some resilience if one worker gets stuck or GC-paused, and lets you roll restarts without downtime.
|
|
- **The bigger win is the shared `AsyncClient` refactor.** Right now every request creates and tears down a connection pool. With a shared client you get connection keepalive reuse, which means less TCP handshake overhead and faster responses under load.
|
|
|
|
Want me to do both — bump workers to something reasonable (like 4) and refactor to a shared AsyncClient? With multiple workers you'd just instantiate the client per-worker via the lifespan, which works cleanly.

[Tue 2026-05-05 06:35 UTC] I dont care about overhead or speed. I only care about not being limited. This container has alot of replicas on big machines, My issue is I see `Idle timeout reached for "http://127.0.0.1:8100/v1/chat/completions".` in my sentry logs and wasnt sure if thats the error we just fixed or something else
|
|
assistant: That's the same root cause. Here's the chain:
|
|
|
|
1. Normalizer's httpx client (was 300s timeout) waits for vLLM to respond
|
|
2. vLLM is slow, takes longer than the **fronting proxy's idle timeout** (nginx/envoy/whatever)
|
|
3. Fronting proxy gives up → `Idle timeout reached` in Sentry
|
|
4. Meanwhile the normalizer's httpx call eventually times out too → unhandled `ReadTimeout` → traceback spam (the error you showed me)
|
|
|
|
So your fronting proxy is timing out **before** the normalizer even gets a chance to respond. The fix I just made stops the traceback spam and returns a clean 504, but the **idle timeout** is still gonna happen if the proxy's timeout is shorter than however long vLLM takes.
|
|
|
|
Two things to check:
|
|
|
|
1. **What's your fronting proxy's idle/keepalive timeout?** If it's something like 60s or 120s, that's your ceiling — no matter what httpx timeout you set, the proxy will cut the connection first.
|
|
2. **For streaming requests** this shouldn't be an issue since SSE chunks keep the connection alive. The idle timeout is only hitting you on **non-streaming** requests where the normalizer holds the connection open waiting for the full response.
|
|
|
|
What's sitting in front of this — nginx, envoy, an ingress controller? And do you know the idle timeout on it?
