python - Python子进程进程Popen在一段时间后暂停

Question

所以我有一些代码可以运行我的 Minecraft 服务器并使用子进程获取日志，但是在运行一段时间后，它会出现一些无法删除文件错误，服务器和程序继续运行，但不和谐机器人死了，它暂停收听过程。

@bot.event
async def on_ready():
    channel = bot.get_channel(895697946887200818)
    process = subprocess.Popen("start.bat", stdout=subprocess.PIPE)
    text = ""
    ready = False
    for c in iter(lambda: process.stdout.read(1), b''):  # replace '' with b'' for Python 3
        if not ready:
            if c.decode("utf-8") != "":
                if c.decode("utf-8") == "\n":
                    if text.strip() != "":
                        print(text)
                        if '[Server thread/INFO]: Done' in text.strip():
                            await channel.send("server is ready!")
                            ready = True
                        text = ""
                else:
                    text += c.decode("utf-8")
        else:
            if c.decode("utf-8") != "":
                if c.decode("utf-8") == "\n":
                    if text.strip() != "":
                        await channel.send(text)
                        text = ""
                else:
                    text += c.decode("utf-8")

这是错误

此时它仍在运行，即使在最后一个错误行之后。C:\Users\colin\OneDrive\Desktop\spigot 1.17>暂停
