</div>
<div style="direction: ltr; font-size: 9.75pt; color: rgb(0, 0, 0);">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".</div>
<div style="direction: ltr; font-size: 9.75pt; color: rgb(0, 0, 0);"><br>
</div>
<div style="direction: ltr; font-size: 9.75pt; color: rgb(0, 0, 0);">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.</div>
<div style="direction: ltr; font-size: 9.75pt; color: rgb(0, 0, 0);"><br>

when you setup your own acceptor. Anything you're doing that doesn't parallel a call in my example should be suspect.</div>

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.</div>
