In the case of an emergency exit of a program, the kernel of the Linux operating system can form a pre-mortem memory dump of the program. With this dump, you can often find a place in the program that caused the emergency stop. To enable the possibility of generating the pre-mortem memory dump of program by the Linux kernel, you need to execute the commands:
# Check the possibility of generation of memory dumps
# Specifies the "core" if it is enabled
cat /proc/sys/kernel/core_pattern
# Enabling the generation of memory dumps
echo "core" > /proc/sys/kernel/core_pattern
