去二进制，试图在ESXI环境中运行shell命令失败

Question

下面是我的代码

package main

import (
    "bytes"
    "fmt"
    "io"
    "os"
    "os/exec"
)

func main() {
    sh := "/bin/sh"
    flag := "-c"
    command := "ls -l"
    fmt.Println("program is running")

    result, err := RunCmdAsText(sh, flag, command)
    if err != nil {
        fmt.Println(err)
        return
    }
    fmt.Println(result)
}

func RunCmdAsText(sh string, flag string, command string) (string, error) {
    cmd := exec.Command(sh, flag, command)

    old := os.Stdout
    defer func() {
        os.Stdout = old
    }()
    r, w, _ := os.Pipe()
    os.Stdout = w
    os.Stderr = w

    cmd.Stdout = w
    cmd.Stderr = w

    err := cmd.Start()
    if err != nil {
        return "", err
    }

    err = cmd.Wait()
    if err != nil {
        return "", err
    }

    outC := make(chan string)
    go func() {
        var buf bytes.Buffer
        io.Copy(&buf, r)
        outC <- buf.String()
    }()

    w.Close()
    out := <-outC
    return out, nil
}

，基本上试图通过Golang运行Shell命令。

当我尝试在ESXI-670中运行它时，

program is running
fork/exec /bin/sh: no space left on device

这是我尝试过的错误：

1. 我尝试使用cmd.output（）尝试执行此操作。
2. 我尝试使用
3. 上述代码中使用CGO_ENABLED = 1进行构建，我尝试通过重定向OS.Stdout进行运行。

除ESXI以外，此代码在所有位置都可以使用并提供所需的输出。我正在使用ESXI-6.7.0。

请帮助我确定原因。

1. 我敢肯定，设备上剩下的空间

以下是Strace的输出：
