Engineering Logs for Troubleshooting & Debugging
Problem Description In a development sandbox that runs Meta LLaMA (v1) on a single NVIDIA A100 GPU, query latency jumped from an average of 150 ms to > 800 ms** within a two‑hour window. The workload is low‑concurrency (1‑5 queries per minute) and uses the default inference script from the Meta LLaMA 2 Documentation. The spike broke … Read more
Problem Description When using Meta LLaMA for Retrieval‑Augmented Generation (RAG) on a workstation with 16 GB RAM and an NVIDIA RTX 3060, the DocumentLoader crashes as soon as it encounters a text file larger than roughly 10 GB. The failure manifests as a series of memory‑related exceptions and, eventually, a hard termination of the Python process. Typical error output: … Read more
Problem: RAG Inference Query Decomposition Failure in Meta LLaMA In a multi‑tenant managed service built on Meta LLaMA 2, the Retrieval‑Augmented Generation (RAG) pipeline is expected to split a user prompt into logical sub‑queries, embed each sub‑query, and retrieve relevant documents from tenant‑isolated indexes. Recent incidents show that complex, multi‑sentence prompts are either truncated or produce empty sub‑queries, … Read more
Problem – Webhook Timeout During Canary Deployment of Meta LLaMA During a canary rollout on an Amazon EKS cluster, 10 % of traffic was routed to a new version of the Meta LLaMA inference service. The service invokes an external monitoring endpoint via a REST webhook after each inference request. Operators observed a surge in failed … Read more
