 - If the server hangs during initialization or running, it can be memory issues (out of memory), network issues (nccl errors), or other bugs in sglang.
     - If it is out of memory, you might see that `avail mem` is very low during the initialization or right after initialization. In this case,
       you can try to decrease `--mem-fraction-static`, decrease `--cuda-graph-max-bs`, or decrease `--chunked-prefill-size`.

 To achieve more deterministic outputs in the current code, you can add `--disable-radix-cache` and send only one request at a time. The results will be mostly deterministic under this setting.

-Recently, we also introduced a deterministic mode, you can enable it with `--enable-deterministic-inference`. It might not work for all cases.

+# Production Request Tracing
+
 SGlang exports request trace data based on the OpenTelemetry Collector. You can enable tracing by adding the `--enable-trace` and configure the OpenTelemetry Collector endpoint using `--otlp-traces-endpoint` when launching the server.
 
 You can find example screenshots of the visualization in https://github.com/sgl-project/sglang/issues/8965.
