[IronPython] Calling WCF service

We are using channel Factory for calling WCF service in ironpython. But when
we give call to a method in that service, the method is not called and it
shows CPU usage almost 100%.
This method takes the request object and returns response.

I am giving the code snippet here.

This is in config file


<endpoint address="net.tcp://"
binding="netTcpBinding" bindingConfiguration="BusinessNetTCPBinding"
name="MessagingServiceEP" />

in program.py

import clr


import System
import System.ServiceModel

from System.ServiceModel import *


from OnlineAVL.Services.Messaging.Interface import *

_factory = ChannelFactory[IOnlineAVLMessagingService]("MessagingServiceEP")
service = _factory.CreateChannel();

# request object is populated here
req = Request();

print "calling"
#call to method

print res

When we execute this, on console it prints "calling" and after that CPU
usage goes up to 100%, and the machine becomes extremely slow and then gives
OutOfMemory Exception. It does not call the service method also.
Any solution to this problem?
Thanks in advance.
