Quick Reference

Goroutine Leaks

• Goroutine blocked on channel with no sender = leak forever—always ensure channel closes or use context
• Unbuffered channel send blocks until receive—deadlock if receiver never comes
• for range on channel loops forever until channel closed—sender must close(ch)
• Context cancellation doesn't stop goroutine automatically—must check ctx.Done() in loop
• Leaked goroutines accumulate memory and never garbage collect
