How do I investigate goroutine leaks?

Goroutine leaks can lead to performance issues in Go applications, making it essential to investigate and resolve them promptly. Below are some strategies and example code snippets available to identify and fix goroutine leaks.

// Example of detecting goroutine leaks in Go
package main

import (
    "fmt"
    "time"
)

func leakingGoroutine() {
    for {
        time.Sleep(1 * time.Second)
        fmt.Println("Still running...")
    }
}

func main() {
    go leakingGoroutine() // This goroutine will leak
    time.Sleep(5 * time.Second)
    fmt.Println("Main function exiting")
}
