<p>I suspect, given that the server_id is not showing in the usrloc dump, this is exactly why the server_id filtering is not working.</p>
<p>We need to understand first why server_id is not present, before moving on to the keepalives.</p>
<p>I have run a test locally with two registrar nodes (server_ids 1 and 2) and two subscribers, each registering to a different node.</p>
<p>Output of ul.dump on one of the nodes:</p>

<p>As you can see, server_id is present in both contacts and showing the correct value(s).</p>
<p>Can you paste the output (or a snippet) of the same command on one of your nodes?</p>
