Python: xmlrpc out of memory when sending binary -

-

i got simple xmlrpc server script written in python. limited memory 512mb simulate environment script running.

import simplexmlrpcserver import resource  memory_limit = 512 resource.setrlimit(resource.rlimit_as, (memory_limit * 1048576l, -1l))  class functions:   def foo(self, file):     print "received file"  server = simplexmlrpcserver.simplexmlrpcserver(("localhost", 8000)) server.allow_none = true server.register_instance(functions()) server.serve_forever()

then got client script:

import xmlrpclib import sys  client = xmlrpclib.server('http://localhost:8000')  file = open(sys.argv[1], 'r') binary = xmlrpclib.binary(file.read())  client.foo(binary)

when send file of 20mb, following exception:

xmlrpclib.fault: <fault 1: "<type 'exceptions.memoryerror'>:">

why can't send 10mb file server has 512mb of memory?
