<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">Sorry for the delay in getting back to you. Essentially we run our FIX engine inside a Windows Service so if for whatever reason someone
stops the service we try and shutdown our sessions neatly. However the main thing is at the end of every day we have to shut down the FIX engine to remove locks on the log files so that we can perform housekeeping/archiving of the files. This is done when
all sessions have completed and logged out for the day (Using login/logout times as you mentioned). However on very rare occasions QuickFix is throwing the unhandled exception shown in my previous email and shown again below which then crashes our Windows
Service completely. I have seen other people raise this issue and it potentially seems to be a bug in the QuickFix engine itself however I wanted to check that it wasn’t related to the way I was shutting down the engine at the end of the day.<o:p></o:p></span></p>

<p class="MsoNormal">Could you provide a little background on what your use case is for stopping particular Sessions manually?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">It is more typical to let the Initiator manage stopping and starting Sessions for you, e.g. using the StartTime/EndTime SessionSettings, or by calling Stop() on the Initiator itself to stop all Sessions.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Depending on your use case the Initiaiator's AddSession/RemoveSession methods might be useful to you. See: <a href="https://github.com/connamara/quickfixn/blob/master/QuickFIXn/AbstractInitiator.cs#L130-L157">https://github.com/connamara/quickfixn/blob/master/QuickFIXn/AbstractInitiator.cs#L130-L157</a><o:p></o:p></p>
