Debugging procedure

• Login as root
• ulimit -c unlimited
  • Check with ulimit -c
• vi /etc/security/limits.conf and add:

  *               soft    core            unlimited
  *               hard    core            unlimited

• To save core dumps in /var/dumps, run:
  • mkdir -p /var/dumps
  • chmod 1777 /var/dumps
  • Check permissions: ll -d /var/dumps should result in something like:
    • drwxrwxrwt 2 root root 4096 13 aug 14:52 /var/dumps (black text on green background)
  • Make sure /var/dumps has enough empty space
  • echo /var/dumps/core.%e.%p | tee /proc/sys/kernel/core_pattern
• reboot
• After reboot login as root in a terminal again and check with ulimit -c
  • It should return unlimited
    • If not, run ulimit -c unlimited and check again with ulimit -c
• Make a program crash and check if a core dump is created in /var/dumps

Replace “/var/dumps/core.%e.%p” from /proc/sys/kernel/core_pattern with “core” # Without the double quotes
