Richard Oudkerk added the comment: Why are you connecting to a multiprocessing listener with a raw socket? You should be using multiprocessing.connection.Client to create a client connection.
Connection.send(obj) writes a 32 bit unsigned int (in network order) to the socket representing the length of the pickled data for obj, followed by the pickled data itself. Since you are doing a raw socket write, the server connection is misenterpreting the first 4 bytes of your message "abcd" as the length of the message. So the receiving end needs to allocate space for struct.unpack("!I", "abcd")[0] == 1633837924 ~ 1.5Gb causing the MemoryError. ---------- nosy: +sbt resolution: -> invalid stage: -> committed/rejected status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue16920> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
