Problem – OOM and CPU Saturation Under Concurrent Vector Search & Embedding Ingestion In a production Retrieval‑Augmented Generation (RAG) service the Elasticsearch cluster receives >15 k requests / second. Each request either: Executes a k‑nn similarity search on a dense_vector field. Streams newly generated embeddings via bulk indexing. During peak traffic the following symptoms appear on the hot … Read more

Problem Description On‑premise LLM inference nodes equipped with NVIDIA GPUs (e.g., A100 40 GiB, RTX 3090 24 GiB) crash when processing prompts that exceed the pre‑allocated key‑value (KV) cache size. The failure manifests as a CUDA out‑of‑memory (OOM) exception during the attention kernel launch. Typical log excerpts: [2026-08-10 14:32:07] ERROR – torch.cuda.OutOfMemoryError: CUDA out of memory. Tried to allocate 2.00 … Read more
