To debug a Go program panic, follow a systematic methodology to reproduce the error, read the stack trace, and gather evidence. Use Delve to step through code or add incremental logging to pinpoint the root cause.

Finding deadlocks and flaky behavior in Go services requires using the race detector to identify concurrency issues and GODEBUG for deeper investigation. Establish a hypothesis and gather evidence to resolve the root cause.

pprof works by profiling Go programs to identify performance bottlenecks causing high CPU or memory usage. It provides detailed runtime data to help analyze and resolve resource consumption issues during development or production.

Yes, you can use Delve and the race detector together to troubleshoot Go concurrency bugs. The race detector identifies data races while Delve helps step through code to analyze the exact execution flow causing the issue.

Your Go program may hang due to deadlocks or concurrency issues. Diagnose it using production diagnostics techniques, GODEBUG settings, and pprof to gather runtime evidence and identify the blocking operation.

You need to use GODEBUG for troubleshooting Go applications when investigating deeper runtime behaviors not visible through standard logging. It helps analyze garbage collection, scheduling, and other internal execution details.
