Running a debug python from the py3k branch on my windows 7 machine, 64 bit, test_multiprocessing hangs in the _TestZZZNumberOfObjects test. I don't know this module, but I did a little digging: The main process is in the gc.collec() causing some manager object to call a _decref() method, which is initiating a socket connection to a child process (I presume.) This is spinning endlessly because the connection is constantly refused. The child processes don't have any sockets open (according to the resource monitor) and when I look at the state they are in, the are stuck waiting for a ReadFile to succeed. The python traceback appears to be (innermost first, line numbers approximate:) queues.py:349 pool.py:45 process.py:83 process.py:215 forking.py:326 |
