Re: [SR-Users] Kamailio fail to start with db_mongodb and ndb_mongodb modules

2 Jan 2018

      Hello,
the issue happens inside mongoc library. Have you tried with the default
one from Debian, without compiling it from sources?
Cheers,
Daniel

Hi,
My last email was help for admin review.
Sharing logs through pastebin https://pastebin.com/6HhdYLJK
Interesting part will start from line 983 where it start initializing
ndb_mongodb.

Hi,

I enabled but kamailio didn't generate any dump file
To enable code dump followed
https://www.kamailio.org/dokuwiki/doku.php/troubleshooting:corefiles
<https://www.kamailio.org/dokuwiki/doku.php/troubleshooting:corefiles>

I also un-commented lines in /etc/init.d/kamailio script

if test "$DUMP_CORE" = "yes" ; then
    # set proper ulimit
    ulimit -c unlimited

    # directory for the core dump files
    COREDIR=/tmp/corefiles
    [ -d $COREDIR ] || mkdir -p $COREDIR
    chmod 777 $COREDIR
    echo "$COREDIR/core.%e.sig%s.%p" > /proc/sys/kernel/core_pattern
fi

I think reason is that kamailio process didn't exit after crash
and keep on restarting. each time with new PID. 

However, debug file is attached. I hope this will help.

        error 6 means, fault is

        |* bit 2 == 1 means kernel, 1 means user-mode * bit 4 == 1
        means fault was an instruction fetch |

        That looks like kamailio is trying to invoke for db
        connection where libmongo-c don't like to be.

            kamailio.service entered failed state.

            As I tried googling the issue and found few issues
            with tls connection.
            I set in default kamailio.cfg but still facing the
            saem issue.

            enable_tls=no
            ...
            loadmodule "ndb_mongodb.so"
            modparam("ndb_mongodb", "server",
            "name=cgr91rc8;uri='mongodb://localhost/kamailio'")

            Its mongodb default installation and its accessible
            without any auth yet.

            Please suggest the way farward.
