write tcp 127.0.0.1:46438->127.0.0.1:36667: use of closed network connection

Rod Version: v0.113.3

最近发现日志里面有一些 panic

write tcp 127.0.0.1:46438->127.0.0.1:36667: use of closed network connection

我这边是与 gin 搭配使用，首次运行时会初始化浏览器

func InitBrowser() {
	u := launcher.New().
		Set("no-sandbox").
		Set("disable-setuid-sandbox").
		Set("disable-gpu").
		Set("disable-dev-shm-usage").
		Set("unlimited-storage").
		Set("disable-accelerated-2d-canvas").
		Set("full-memory-crash-report").
		MustLaunch()
	RodBrowser = rod.New().ControlURL(u).MustConnect()
}

然后封装了一个接口，来生成 PDF，关键代码如下

p := RodBrowser.MustPage(url).MustWaitLoad()
defer p.MustClose()

wait := p.MustWaitRequestIdle()
wait()

// 等待元素可见
elem := p.MustElement(visibleDom)
elem.MustWaitVisible()

log.Println(url, "页面已经渲染好了，开始生成 PDF ")

pdf, err := p.PDF(&proto.PagePrintToPDF{
PaperWidth:      gson.Num(paperWidth),
PaperHeight:     gson.Num(paperHeight),
PrintBackground: true,
MarginTop:       gson.Num(marginTop),
MarginBottom:    gson.Num(marginBottom),
MarginLeft:      gson.Num(marginLeft),
MarginRight:     gson.Num(marginRight),
})

目前总是运行一段时间后，出现那个 panic 错误，重启后就可以恢复，没什么排查思路，请大佬帮忙看看

抱歉，如果难以稳定复现的话我也不知道怎么帮忙

我在考虑，是否是因为我全局初始化了，然后运行了一段时间后浏览器崩溃了

如果是在Linux系统下运行的，考虑是否是共享内存用尽了，因为 Chrome 在Linux下会使用共享内存， dev-shm 使用命令行 flag ’–disable-dev-shm-usage 可以进行禁用

[ysmood]

@Fly-Playgroud 默认是禁用了呀

rod/lib/launcher/launcher.go

Line 76 in 2e5e465

"disable-dev-shm-usage": nil,

@endachao 你试试最新版的 rod，说不定就没有问题了

这可能是最近的版本加的吧，至少在0.113 版本上没有

感谢两位回复，我确认我在启动前，已经设置了 disable-dev-shm-usage 这个参数了

func InitBrowser() {
	u := launcher.New().
		Set("no-sandbox").
		Set("disable-setuid-sandbox").
		Set("disable-gpu").
		Set("disable-dev-shm-usage").   // 在这里已经设置为 disable 了
		Set("unlimited-storage").
		Set("disable-accelerated-2d-canvas").
		Set("full-memory-crash-report").
		MustLaunch()
	RodBrowser = rod.New().ControlURL(u).MustConnect()
}
