<font face="Helvetica, Arial, sans-serif">"0" simply means "to
infinity", i.e. the most current seqnum that is used on receiver
side.<br>

<div>I created a pair of test apps, a sender and a receiver.</div>
<div>They are connected and the sender is sending execution
reports and then I kill the receiver to simulate failure.</div>
<div><font face="Times New Roman"> </font></div>
<div>I see an event entry, “Sent ResendRequest FROM: 86820 TO:
0” on the receiver side.</div>
<div>It seems to be asking for all messages from 86820 (either
including/excluding, not sure) to 87211 (again not sure, I’m
guessing excluding).</div>
<div>The “0” is what throws me.</div>
<div><font face="Times New Roman"> </font></div>
<div>Can someone describe in detail what’s happening? Or point
me to a documentation of how this works?</div>
