  • Goroutine states: RUNNABLE vs. BLOCKED vs. SYS/IO; many BLOCKED goroutines waiting on channel/lock may indicate leaks.
  • Large counts of identical stack traces usually mean a goroutine-creation hotspot.
  • Heap top types show where memory is concentrated — strings, slices, maps are common culprits.
  • Inspect object retainers to see why memory is not GC-collected (references from global variables, caches, or long-lived goroutines).
  • Use the pprof heap/profile in tandem with xdumpgo to correlate allocation sites with live objects.

3. Trace Goroutine IDs from a Core Dump

  • Visual: Coding a User struct with fields.
  • Audio: "Let's write a simple dump. Watch how it formats the output compared to fmt."
  • Highlight: Show the output difference side-by-side.
