Core dump file

set the core dump file limit as unlimited by using

ulimit -c unlimited

And also check the path of core dump generation, normally the core dump is generated in the current directory of the process but by giving the path in /proc/sys/kernel/core_pattern you can change the path and name of core generation, something like below

echo /var/log/mycore > /proc/sys/kernel/core_pattern

now the core would be generated as /var/log/

Please also refer the man core, if you still don't see the core then send us the output of below command cat /proc/sys/kernel/core_pattern
