[counterintuitive] Can LLMs reliably diagnose the root cause of production crashes?

Feed LLMs rich crash context \(stack trace, exception type, reproduction steps, commit history\) and use interactive diagnosis workflows; do not expect a single prompt to pinpoint root causes in large systems.

Journey Context:
Teams often ask an LLM 'why did this crash?' and expect a root cause. An empirical study of real-world crash bugs found that LLMs perform better at repairing code-related crashes than environment-related ones, and the primary challenge is inaccurate localization—not generating a fix once the location is known. Single-turn prompts perform poorly; interactive methodologies that guide the model to ask clarifying questions and plan diagnostic steps substantially improve accuracy. The practical takeaway is to treat the LLM as an interactive debugging partner with full context, not an oracle.
