Also; try to come up with some reproducible code that illustrates the problem.

Is this yours btw? https://github.com/zeromq/libzmq/issues/4358

I guess it is. Try to see if you can get any errors out of your code.
I'm not familiar with the Python wrapper but usually the recv and send calls return something. If your code freezes, make sure you know where.

Would be helpful to test this code directly against libzmq instead of through python.

Rg,

Arnaud

Hi Momchil,

Windows does not provide IPC sockets.
you'll have to stick to TCP sockets

cheers,

    Hello,

    I have a client server poc code that runs ok in user mode
    it uses zmq.REQ context and an IPC socket to send over json and
    receive back json

    problem is when I wrap the server part in win32service code
    both service and client app run under the same user but I still fail
    to send data over
    works just fine if I switch to TCP socket

    PoC code:

    https://github.com/bozhinov/cache-poc
    <https://github.com/bozhinov/cache-poc>

    Environment:

    libzmq version: pyzmq 14.1.1, libzmq 4.3.4

    OS: Windows Server 2022

    Python 3.10.2 x64

    Is this even supposed to work?

    Momchil
