Hi,

I also have the same problem with kamailio 3.1

I made a modification to the file daemonize.c because if lim.rlim_cur is set to -1 the test with size parameter at line 491 do not work because rlimit parameters are unsigned int.

             newlim.rlim_max=RLIM_INFINITY;
             newlim.rlim_cur=newlim.rlim_max;

Thanks to this patch the core dump should be generated.

This work for me on my testing servers, BUT with my production servers (debian 5.0.1) where the core is not generated and I cannot understand why...

Hi everybody,

We are having an uncontrolled crash in Kamailio 3.1:

May 10 20:34:51 tip1 /usr/local/kamailio-3.1/sbin/kamailio[23366]: : <core> [pass_fd.c:293]: ERROR: receive_fd: EOF on 39

I've read in several posts I must generate the "Core Dump" to know what is happening. I'm trying to generate it in this way.

"/etc/init.d/Kamailio" file:
if test "$DUMP_CORE" = "yes" ; then
1. set proper ulimit
ulimit -c unlimited
directory for the core dump files
COREDIR=/dumps/
[ -d $COREDIR ] || mkdir $COREDIR
chmod 777 $COREDIR
echo "$COREDIR/core.%e.sig%s.%p" > /proc/sys/kernel/core_pattern
fi 


"/etc/default/Kamailio" file:
DUMP_CORE=yes


But the core is not yet generated.

Then I've added -w option:

OPTIONS="-P $PID_FILE -m $MEMORY -u $USER -g $GROUP -w /dumps/"

But core still not generated

In "kamailio.cfg" I´ve also added:
disable_core_dump=no 


User running Kamailio is "kamailio" who has 777 permissions in /dumps/ directory. No way.


Anyhelp would be appreciated.

Cheers,

Ricardo Domínguez
