[OpenSIPS-Users] random segfaults without generating core file

[Duane Larson]

And you're sure you have enabled Core dumps in the /etc/init.d/opensips
file?

if test "$DUMP_CORE" = "yes" ; then
    # set proper ulimit
    ulimit -c unlimited
    # directory for the core dump files
    COREDIR=/home/opensips/corefiles
     [ -d $COREDIR ] || mkdir $COREDIR
     chmod 777 $COREDIR
     echo "$COREDIR/core.%e.sig%s.%p" > /proc/sys/kernel/core_pattern
fi
