investigate

Root cause debugging requires systematically investigating error messages, stack traces, and code paths. You gather evidence, reproduce the failure, hypothesize the true cause, and validate it before implementing a fix to ensure the actual issue is resolved.

Troubleshooting with stack traces involves analyzing the call sequence to locate the exact failure point. You trace the error through the code paths, reproduce the steps consistently, and identify recent changes that triggered the exception.

Yes, reproducing and validating bugs is essential before fixing. You capture deterministic reproduction steps and error evidence, then verify your hypothesis against the actual failure conditions to ensure the fix addresses the true root cause.

Root cause debugging supports intermittent failures by enforcing evidence capture and deterministic reproduction workflows. You analyze logs and stack traces to find consistent patterns, then validate hypotheses against edge cases before implementing the fix.

A four phase workflow—investigate, analyze, hypothesize, implement—prevents patching symptoms. It enforces evidence gathering and root cause validation, ensuring your fix resolves the actual failure and captures learnings for future troubleshooting.
