Errno 32 Broken pipe, Errno 107 Transport endpoint is not connected python socket

Question

My TCP Server is written in Qt 4.7, works well with TCP Client also written in Qt 4.7.

I am trying to connect and communicate with Server with client written in python 2.7.3. I start the Server process via apache http request with subprocess.call(path_to_server). I am using mod_wsgi 3.3 and django 1.4.

Connection is established without a problem. I am receiving [Errno 32] Broken pipe exception on socket.send() randomly (I can spam same msg for 10 times and it will be sent 0-10 times). Same happens to socket.shutdown() & socket.close(), I can spam disconnect command and it will randomly disconnect, otherwise receiving [Errno 107] Transport endpoint is not connected exception.

netstat -nap says connection is established.

When I try running same client script using python2.7 shell everything works fine.

What am I missing here?

EDIT Everything works on Windows 7, running same apache,mod_wsgi,python,django configuration. TCP Server is also Windows compatible. Error happens on centos6.2 32bit.

Answer 1

I had to set apache settings to following: KeepAlive On MaxKeepAliveRequests 0 KeepAliveTimeout 5

I will further investigate the problem and see if this is proper solution.
