Nothing Crashed. Nothing Errored. My CPU Sat at 390% for an Hour.
TL;DR: A bug-reporting story from DEV's Summer Bug Smash describes an unusual CPU spike lasting an hour with no crashes or errors. The user details diagnostic steps and reflections on how to approach such silent performance issues.
The author participated in a bug-smash event and observed that the CPU utilization spiked to 390% for an hour without any crashes or error messages. They attempted typical diagnostics and monitored system behavior to identify root causes. The narrative emphasizes the challenge of tracing performance issues that leave no obvious failures. The piece underscores the importance of observability and structured debugging in real-world scenarios.
Question for the room: What unusual performance issue have you diagnosed without clear errors, and how did you identify the root cause?
