Hello,

 

it might be something related to the ARM compilation, that maybe the build system does not generate proper debug symbols here.

 

I need to check on my Rasberries as well, but do not remember problems last time I compiled it there.

 

Cheers,

 

Henning

Hi Daniel,

 

I followed this guide: https://kamailio.org/docs/tutorials/5.5.x/kamailio-install-guide-git/

How did you compile kamailio? The binaries do not contain the debugging symbols...

Are you compiled Kamailio from sources?

 

If compiled from sources or installed "debug" files then pelase show output of "bt full" command.

Daniel,

 

Thank you. That finally helped getting the core file written. Here is the gdb output:

What can be done about that?

Thank you for your response.

 

I'm trying to run it under gdb but it's not doing anything:

 

```

(gdb) exec-file /usr/sbin/kamailio
(gdb) set args -f /etc/kamailio/kamailio.cfg -D -d -E
(gdb) run
Starting program: /usr/sbin/kamailio -f /etc/kamailio/kamailio.cfg -D -d -E
warning: Error disabling address space randomization: Success

```

 

It just stops there. Am I missing something?

You can start kamailio under GDB debugger.

When issue reproduced, then you can get stack trace and variables values

Greetings,

 

I'm having a "fun" time trying to run Kamailio inside a Docker container. It keeps failing with:

 

 0(238) DEBUG: <core> [core/mem/pkg.c:108]: pkg_print_manager(): pkg - using memory manager: q_malloc
 0(238) DEBUG: <core> [core/mem/shm.c:300]: shm_print_manager(): shm - using memory manager: q_malloc
Illegal instruction (core dumped)

 

Unfortunately the core dump is nowhere to be found. I have tried to follow the instructions at:

 

 

but that hasn't helped.

 

The environment is as follows:

 

* Host hardware: Raspberry Pi 4 (4G memory)

* Host OS: Ubuntu 20.04.1 LTS

* Docker version 19.03.13

* Docker base image: arm32v7/ubuntu

 

root@2ef8a21534fa:/# kamailio -v

id: unknown
compiled with gcc 9.2.1

 

The config file passes the syntax check:

 

    kamailio -c -f /etc/kamailio/kamailio.cfg

 

and, the most interesting part, if I run Kamailio on the host machine, _with the exact same config file_, it runs fine.

 

I'd appreciate any clues you may have. Thanks.
