<div dir="ltr">Greetings,
<div><br>
</div>
<div>I'm having a "fun" time trying to run
Kamailio inside a Docker container. It keeps
failing with:</div>
<div><br>
</div>
<div> 0(238) DEBUG: <core>
[core/mem/pkg.c:108]: pkg_print_manager(): pkg -
using memory manager: q_malloc<br>

using memory manager: q_malloc<br>
Illegal instruction (core dumped)<br>
</div>
<div><br>
</div>
<div>Unfortunately the core dump is nowhere to be
found. I have tried to follow the instructions
at:</div>

</div>
<div><br>
</div>
<div>but that hasn't helped.</div>
<div><br>
</div>
<div>The environment is as follows:</div>
<div><br>
</div>
<div>* Host hardware: Raspberry Pi 4 (4G memory)</div>
<div>* Host OS: Ubuntu 20.04.1 LTS</div>
<div>* Docker version 19.03.13</div>

</div>
<div><br>
</div>
<div>The config file passes the syntax check:</div>
<div><br>
</div>
<div> kamailio -c -f /etc/kamailio/kamailio.cfg<br>
</div>
<div><br>
</div>
<div>and, the most interesting part, if I run
Kamailio on the host machine, _with the exact
same config file_, it runs fine.</div>
<div><br>
</div>
<div>I'd appreciate any clues you may have.
Thanks.</div>
