{{Quickfixn}} Sending Email Message Problem

[somnath pal]

One more point I should mention. I am developing this software for a firm. Due to whatever reasons they might have, I don't know why, they told me not to use NeGet package, but use the source code of the package. So I am using the QuickFixn source code in a class library and not using NeGet package.

Thanks,
Somnath

I was not sure, why the email problem was happening. After investigation I am getting more and more information and sharing with you as I found. Answer of your questions:

1. ‎Yes 1.13.1 (.Net 8) is used. I am migrating to .Net Core

2. Start button click:
    Creates the acceptor socket and starts
    DualEngineAcceptor = new ThreadedSocketAcceptor(application, storeFactory, settings, logFactory, messageFactory);
    DualEngineAcceptor.Start();

     *


    Stop button click: DualEngineAcceptor.Stop();

3.  ConnectionType=acceptor, so it's acceptor. No need for counter party. Error happanes with or without connection to counter party initiator. So, counter party is not important here.

To reproduce the problem, with or without connection to counter party initiator,

A) Start button 1st click - all good
B) Stop button 1st click - all good
C) Start button 2nd click - error
D) Start button 3rd click - all good

So looks like, when the error happened at step C, all are reset and Step D worked. Probably, that reset hapenning at Step C, should have been also at Step B when Stopped.

Thanks,
Somnath

Ok, now you're telling me new things that would have been useful to know earlier.  You never said anyting about that File Store exception-- that's important!  Your questions and answers are kind of disorganized, it's a little hard to follow.

1. Are you sure you're using the latest release v1.13.1?  (".net8" is not a QF/n version.)

2. I don't need to know what your UI looks like.  Are your buttons calling acceptor.Start and acceptor.Stop?

3. Is that config for your Initiator or for your Acceptor?  What is the config on the other side?

4. The store error on stop/restart should not be happening.  I will try and find time to spin up a sample app and see if I can replicate it.

By the way, if you want to stick with your old C#-over-C++ wrapper until we figure this out, you could use Stunnel to wrap SSL around that connection.
