<br>When we asked the support they said that they didn't receive any heartbeat from our end so they closed the connection. <br><br>When we look at our FIX log files we see that time between our last heartbeat and the last snapshot from the server is under 60 seconds. And we didn't receive any logout message from the server either. <br>
<br>Also during all this time the Order Session stayed connected with proper heartbeat message. <br><br><b>Our Questions are: </b><br>Q1: What might have caused the system to not send out a Heartbeat message? <br>Q2: Is it normal for the server to close connection on missing 1 heartbeat message? My understanding was that in case there is no heartbeat from the client, server will send a test request. <br>
Q3: Using QuickFIX/n how can i ensure my periodic heartbeat message? <br>Q4: Whats the best time interval for heartbeat? (Mine is currently set to 60 seconds)<br clear="all">Q5: How can we diagnose to figure out the root cause of this issue?<br>
<br>Thanks,<span class="HOEnZb"><font color="#888888"><br><br>-- <br>//Regards<br>Rasheed<br>
