Where are Linux core dumps stored?

By default, all core dumps are stored in /var/lib/systemd/coredump (due to Storage=external ) and they are compressed with zstd (due to Compress=yes ). Additionally, various size limits for the storage can be configured. Note: The default value for kernel. core_pattern is set in /usr/lib/sysctl.

Where is the core file in Linux?

For the core file to be produced, we need to configure the RLIMIT_CORE (core file size) resource limit for the process, which is set to 0 by default. By default, a file named core will be produced in the application’s working directory. This behavior can be changed writing to /proc/sys/kernel/core_pattern.
