{{Quickfixn}} Sending Email Message Problem

[Grant Birchmeier]

Somnath,

Your report had me worried that we had a problem with Acceptor Stop/Start,
but I'm just not able to reproduce your issue.

Methodology:  I've hacked the "Executor" example app to let me invoke
Stop/Start on the acceptor, and changed it to use a FileLogFactory and
FileStoreFactory.  I've changed its config to set every "ResetOn<X>"
setting to =N.  For an initiator, I used the "TradeClient" example, also
configured with every "ResetOn<X>=N".

I started up the Executor and called Start/Stop repeatedly with no
problems.  Then I restarted it and connected the TradeClient to it, and
again called Start/Stop repeatedly.  The TradeClient was able to reconnect
after every time I called acceptor.Start().  I saw no exceptions on either
side.  The logs and store files contained nothing that I didn't expect to
see.

The Executor and TradeClient example sources are at:
https://github.com/connamara/quickfixn/tree/master/Examples.  I've attached
my modified Executor Program.cs so you can see how I called Stop/Start.

At this point I can only conclude that you are doing something unexpected
in your code.  I think you should have a look at the Executor, and then
compare that to the functions you are calling when you setup your own
acceptor.  Anything you're doing that doesn't parallel a call in my example
should be suspect.

-Grant
