Core file issue - sr-users

4 Jul 2013

Hi,

I am having the problem with core file generation on ubuntu

For some reason the core file is not complete even though ulimit is set to
unlimited

$ullmit -a

core file size          (blocks, -c) unlimited
<----- Unlimitd
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 15891
max locked memory       (kbytes, -l) 64
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 8192
cpu time               (seconds, -t) unlimited
max user processes              (-u) 15891
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

But when core is generated, and I try to open gdb, it is complaining that
the core file is smaller

$sudo gdb /usr/local/sbin/kamailio core

What could be going wrong?
