A technical post explains how to prevent LLM servers from crashing due to memory issues by correctly accounting for KV cache usage. The key insight is that memory reservations should be based on the maximum potential output tokens (prompt + max_tokens cap), not just the current prompt length. This approach prevents intermittent Out-Of-Memory errors that occur when many requests with large generation caps overlap. The post also suggests implementing a Retry-After header to signal clients to back off when requests are rejected due to insufficient resources. AI
