python编写的windows服务不能执行系统命令

Question

我写了一个ＷＩＮＤＯＷＳ程序，监控ＩＰ的某个端口的连接情况，如果直接生成ＥＸＥ是可以运行的，但是当我打包成了服务文件后，运行时却所“句柄无效”，后面一句一句的调试，发现是下面的这个库文件，运行subprocess.Popen时报错了，我把netstat 这个命令改成了其他的命令如：dir之类的，也同样报错，不清楚是不是在ＷＩＮＤＯＷＳ服务中不能使用subprocess.Popen或者有其他的原因？？？？
望大侠帮助

下面是其中调用到的的一个库文件

import subprocess
from Action.SYS.get import *
class System:
    __get=None
    __OS=''
    def __init__(self):
        self.__get=get()
        self.__OS=self.__get.getOS()

    def serverListenByPort(self,address, port, netstatus="ESTABLISHED"):
        result = []
        statuspos=0
        if self.__OS=='Linux':
            subp = subprocess.Popen('netstat -ano | grep %s:%s' % (address, port), shell=True, stdout=subprocess.PIPE)
            statuspos=5
        if self.__OS=='Windows':
            subp = subprocess.Popen('netstat -ano | findstr %s:%s' % (address, port), shell=True, stdout=subprocess.PIPE)
            statuspos = 3
        while True:
            buff = subp.stdout.readline()
            buff = str(buff, encoding='utf-8')
            buffers = buff.split()
            try:
                if str(buffers[statuspos]).strip() == netstatus:
                    buffers.append(self.__OS)
                    result.append(buffers)
            except Exception as e:
                pass
            if buff == '' or buff == None:
                break;
        return result

proc = subprocess.Popen(args,shell=True,stdout=open(outimploc, 'w'), stderr=open(outimplocerr,'w'),stdin = subprocess.PIPE, cwd=self.tranusConf.workingDirectory).communicate()

原来要这样处理，不会报错winerror 6
