you need to change these
check your current core limit with ulimit
root@x:/tmp# ulimit -c
0
0 means no core is generated
root@x:/tmp# ulimit -c unlimited
set it to unlimited or any other value (this is max size of core file)
root@x:/tmp# ulimit -c
unlimited
root@x:/tmp#
root@x:/tmp#
root@x:/tmp# ulimit -a
core file size (blocks, -c) unlimited
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 20
file size (blocks, -f) unlimited
pending signals (-i) 16382
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) unlimited
v irtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
root@x:/tmp#
This will change core limit for current session.
You need to add this in /etc/init.d [file name depends on distribution] so that these values are set when computer boots.
