当浏览器关闭时，chrome_crashpad_handler和Chromium Helper两个进程没有被关闭。

[DC3x6]

Rod Version: v0.114.5

在多协程的情况下，每个协程开始时初始化一个浏览器，浏览器关闭时，chrome_crashpad_handler和Chromium Helper两个进程没有被关闭，导致内存占满。

  func main() {
    var swg = sizedwaitgroup.New(10)
    for i := 0; i < 100; i++ {
        swg.Add()
        go func(num int) {
            defer swg.Done()
            println(num)
            browser := testrod.NBrowser()
            defer browser.MustClose()
            page := browser.Timeout(20 * time.Second).MustPage()
            navigation := page.MustWaitNavigation()
            page.MustNavigate("https://www.google.com/")
            navigation()
            time.Sleep(5 * time.Second)
        }(i)
    }
    swg.Wait()

}

如果 leakless 都不行，那么 chrome 就非常像病毒了。你只能自己处理他的进程了，这是拿到 stdlib 的 cmd 对象的例子：

你使用 exec 库的话就和 rod 无关了，这部分实在难以调试和复现。

var fE = func() error {
        browser.MustClose()

        return nil
    }
    defer func() {
        if err := recover(); nil != err {
            log.Println(err)
            fE()
        }
    }()
    util.NewExit().RegClose(fE)
