<p>In case someone else runs into this issue -- it was far from transparent, but my best guess is it was caused by some combination of file permission issues. These are the various things on CentOS 7 that were tweaked to allow a core dump</p>
<p>The following combination of things were changed:</p>
<p>/etc/sysctl.d/99-sysctl.conf</p>
<pre><code>kernel.core_pattern = /tmp/core.%e.%p.%h.%t
kernel.core_uses_pid=1
fs.suid_dumpable = 2
</code></pre>
<p><code>sysctl --system</code> to reload kernel parameters</p>
<p>/etc/sysconfig/kamailio</p>
<pre><code>DUMP_CORE=yes
</code></pre>
<p>May be required but unclear:<br>
<code>ulimit -c unlimited</code></p>
<p>Tested by running<br>
<code>kill -ABRT <PID of Kamailio Child></code></p>
