Python多处理管理器在启动时阻塞

python SyncManager在我的机器上初始化时似乎有问题

我有以下设置：

在我的主要启动程序中：

if __name__ == '__main__':
    theManager = multiprocessManager.Manager()
    stopEvent = theManager.Event()        # Make sure your daemon stops all threads in a clean way

    log = logging.getLogger('central-queue') # maybe move to mp.getlogger?
    # do some log setup with file and stream handlers
    log.info("Creating process safe Object to keep state of testbeds shared over all work processes")
    testbedObjectsPool = theManager.TestbedInfo()

    log.info("Wait a while before starting other processes to init the tbObjPool")
    stopEvent.wait(100)

    log.info("Starting process to watch the input dir")
    jobFinderProcess = jobFinder.JobFinder(inputQueue, stopEvent)
    jobFinderProcess.start()

在multiprocessManager.py中

from multiprocessing.managers import SyncManager

import testbedInfo

class MultiprocessManager(SyncManager):
    pass

MultiprocessManager.register("TestbedInfo", testbedInfo.TestbedInfoPool, proxytype=None)

def Manager():
    #print "MultiprocessManager.Manager"
    m = MultiprocessManager()
    m.start()
    return m

在testbedInfo.py中

class TestbedInfoPool:
    """Gather all info from all testbeds into this class (ie a bunch of TestbedProperties objects)"""
    def __init__(self):
        # Specific to this class
        self._initDatabase() # creates and configures self.db for us
        self.reset()
        blacklistfile = "%s/testbeds_blacklist_dispatcher.txt" % (os.getcwd())
        self.populateTestbeds(blacklistfile) #Store the offline info into self.dictOfIdTestbedObjects Takes about 2 minutes

当它不工作时，我按下CTRL-C停止挂起过程，我在调试输出中得到以下结果

2017-02-08 09:35:10,141 - INFO - xMainProcessx =MainThread= Creating process safe Object to keep state of testbeds shared over all work processes
Traceback (most recent call last):
  File "./dispatchToTestbed.py", line 117, in <module>
    testbedObjectsPool = theManager.TestbedInfo()
  File "/usr/global/lib/python2.7/multiprocessing/managers.py", line 641, in temp
    token, exp = self._create(typeid, *args, **kwds)
  File "/usr/global/lib/python2.7/multiprocessing/managers.py", line 541, in _create
    id, exposed = dispatch(conn, None, 'create', (typeid,)+args, kwds)
  File "/usr/global/lib/python2.7/multiprocessing/managers.py", line 76, in dispatch
    kind, result = c.recv()
KeyboardInterrupt

有人知道如何进一步调试吗？或者我在这里遗漏了什么

我试图收集的更多信息：

主要流程是根据strace进行此操作：

write(7, "\0\0\0\t#WELCOME#", 13)       = 13
write(7, "\0\0\0'\200\2(NU\6createq\1U\vTestbedInfoq"..., 43) = 43
read(7,

经理流程战略：

Process 26350 attached - interrupt to quit
[ Process PID=26350 runs in 32 bit mode. ]
accept(9,

lsof干管

dispatchT 26321 xxxxxx    7u  unix 0xffff8808212260c0      0t0 637197167 socket

lsof经理

那么这看起来像是主进程试图与manager进程通信，为TestbedInfo启动一个代理，但该进程根本没有收到它吗
