Re: [SR-Users] core dump error when running under docker

Maybe the hints on stackoverflow are also useful:

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

        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:

           
        https://www.kamailio.org/wiki/tutorials/troubleshooting/coredumpfile
        <https://www.kamailio.org/wiki/tutorials/troubleshooting/coredumpfile>

        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
        version: kamailio 5.3.2 (arm/linux)
        flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS,
        USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK,
        SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC,
        DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT-NOSMP,
        USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR,
        USE_DST_BLACKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED
        ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144,
        MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB
        poll method support: poll, epoll_lt, epoll_et, sigio_rt,
        select.
        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.
