<p></p>
<p>Hello.</p>
<p>I have a philosophical question about <a href="https://kamailio.org/docs/modules/5.1.x/modules/tm.html#tm.rpc.clean" rel="nofollow">tm.clean</a> command.</p>
<p>Unfortunately, I don’t understand what this command is for, because in my view, expired transactions are automatically deleted.</p>
<p>This is all I could find:</p>
<blockquote>
<p>pc command tm.clean to clean long time expired transactions (for troubleshooting purposes) <a href="https://www.kamailio.org/wiki/features/new-in-5.1.x" rel="nofollow">[1]</a></p>
</blockquote>
<p>So, can you give an example when a transaction can remain in memory?</p>
<p>Thanks!</p>
