Golang扫描功能中如何处理“错误：IOError：关闭的流”？

I am using knife bootstrap command in Golang code to bootstrap nodes. Some times there is wait in recipe and it waits for more than 10 minutes. In such cases I am getting an error "Error: IOStream Closed". Is there any way I can increase the time limit? Also I am continuously reading the logs from output and error stream of cmd.

func executeCMDWorkstation(cmd *exec.Cmd, projectId, cr_id string) bool {

stdout, err3 := cmd.StdoutPipe()
if err3 != nil {
    utils.Info.Println(err3)
    return false
}
defer stdout.Close()
stderr, err4 := cmd.StderrPipe()
if err4 != nil {
    utils.Info.Println(err4)
    return false
}
defer stderr.Close()

//cmd.Stdout = os.Stdout
//cmd.Stderr = os.Stderr
multi := io.MultiReader(stdout, stderr)
inp := bufio.NewScanner(multi)
err := cmd.Start()
if err != nil {
    utils.Info.Println("Error while creating client", err)
    return false
}
fmt.Println("Generating logs**************")
for inp.Scan() {

    line := inp.Text()
    if cr_id == "" {
        lg.SendDebugLogs(line, "projects/logs", projectId, "chef")
    } else {
        lg.SendDebugLogs(line, "changeRequests/logs", cr_id, "chef")
    }
}
exitStatus := cmd.Wait()
if exiterr, ok := exitStatus.(*exec.ExitError); ok {
    utils.Info.Println("************ Exit Status is:", exiterr, "************")
    return false
}

return true

Any help to improve this process would be highly appreciated.

After looking into some forums, Go Docs and trying some code changes, finally replacing the scan method in bufio to ReadLine of textproto worked for me.

I replaced the following code:

inp := bufio.NewScanner(multi)
err := cmd.Start()
if err != nil {
    utils.Info.Println("Error while creating client", err)
    return false
}
fmt.Println("Generating logs**************")
for inp.Scan() {
    line := inp.Text()
    if cr_id == "" {
        lg.SendDebugLogs(line, "projects/logs", projectId, "chef")
    } else {
        lg.SendDebugLogs(line, "changeRequests/logs", cr_id, "chef")
    }
}

With the following code:

    inp1 := bufio.NewReader(multi)

    tp := textproto.NewReader( inp1 )

    err := cmd.Start()
    if err != nil {
        utils.Info.Println("Error while creating client", err)
        return false
    }
    fmt.Println("Generating logs**************")

    /*
    New code for logs starts here
     */


    for {
        line, readErr := tp.ReadLine()

        if readErr != nil {
                break
        }

        if cr_id == "" {
            lg.SendDebugLogs(line, "projects/logs", projectId, "chef")
        } else {
            lg.SendDebugLogs(line, "changeRequests/logs", cr_id, "chef")
        }
    }

At last, this modification worked perfectly fine for me by handling immediate restarts as well as long sleeps/waits in the chef recipe or scripts. Basically I changed the stream reader I hope this will be helpful for anyone else facing the same problem :)
