  There are few things in MLOps more disheartening than waiting 15 minutes for a large language model (LLM) to deploy, only to watch the CloudWatch logs eventually spit out   Model server exited unexpectedly   or a vague   FailedPrecondition: 400   error. If you are attempting to deploy Meta's Llama 3 (8B or 70B) to AWS SageMaker using Hugging Face Deep Learning Containers (DLCs), you have likely encountered this wall. The logs are often deceptive, suggesting a connection error when the reality is a complex interplay between model weight loading times, health check race conditions, and GPU architecture incompatibilities. This guide provides the root cause analysis and the specific Python code required to successfully deploy Llama 3 on SageMaker, bypassing the default timeout traps. The Root Cause: Why SageMaker Kills Llama 3 To fix the error, you must understand the boot sequence of a SageMaker endpoint. When you call  deploy() , AWS performs the following ...
