Missing Core Dump:
- First, check your core-dump file size limit by running:
ulimit -c
- If the output value is zero (0), programs will not be able to create a core dump.
- To remedy the situation, you need the limit to be above zero.
- You can make the limit as large as possible by running:
ulimit -c unlimited
- Caveats: A new limit only applies to processes started by the current shell. To change it for all processes, put the command in your .profile or .bashrc file.
- Second, on Linux check your the default core dump directory:
cat /proc/sys/kernel/core_pattern
- If this file contains a path and file pattern, core dumps will be written into that path with the corresponding file pattern (assuming the directory is writable and has sufficient disk space).
