[mlx-lm] "[WARNING] Generating with a model that requires N MB which is close to the maximum recommended size" - model near GPU working-set limit, slow generation

Cause (Documented platform behavior): macOS limits GPU wired memory; mlx-lm wires model memory up to the recommended size (macOS 15+). Fix status: documented_behavior Workaround (not a fix): sudo sysctl iogpu.wired_limit_mb=N (resets at reboot). Evidence (public sources, summariz

[Pinecone Python SDK 10] batched upsert returns errors "total_timeout of Xs expired before this batch was submitted" / "backend appears unavailable ... abandoned"

Cause (Documented platform behavior): SDK 10 replaced the per-client limiter with a process-global per-host admission gate: total_timeout bounds admission (not requests) and the gate refuses admission for a 30s cool-down after consecutive all-failed batches at floor concurrency.
