LLM Request Timeout After Inactivity

Monitor for HTTPSConnectionPool timeout errors and increased langchain_chain_error or langchain_llm request failures after periods of low activity. Track time since last successful LLM call and correlate with timeout errors.

Implement connection pool health checks with automatic recreation. Add retry logic with exponential backoff for timeout errors. Configure keep-alive settings on HTTP connections to prevent staleness. Monitor connection pool metrics and preemptively refresh connections before timeout thresholds.
