<p class="MsoNormal">We are currently pushing those messages for a session queue, but eventually want to disconnect the client if the queue is too high, this is where we experience issue as it looks like the QuickFix does not have that option to disconnect
the client, let me know if I'm wrong.<u></u><u></u></p>

<p class="MsoNormal"><u></u> <u></u></p>

<p class="MsoNormal">Another option looks like dropping the message for sending and storing for resend request, however, it still will require disconnecting the client at some point when the storage size for the session will be too high.<u></u><u></u></p>
