<p>Hi,</p>
<p><br>
</p>
<p>I've had a lot of frustrating times with this issue and wanted to mention it before anyone else does.</p>
<p><br>
</p>
<p>Specifically, my erl pipes kept getting deleted, meaning you couldn't attach, or cleanly shutdown services.</p>
<p><br>
</p>
<p>After far too long, I've tracked this to a new systemd service, and found the fix involves editing this file:</p>
<p><br>
</p>
<p><span>/usr/lib/tmpfiles.d/tmp.conf</span></p>
<p><br>
</p>
<p>And telling it not to apply the default ten day lifetime on this folder:</p>
<p><br>
</p>
<p><span>x /tmp/erl_pipes</span></p>
<p><br>
</p>
<p>I'm expecting that will sort it out (although I know now I need ten days to tell).<br>
</p>
