Description
Unattended APT upgrades on the host override the core dump file pattern defined in sysctl.
As a result in a case of a process crash, coredump files were not written to the pre-defined location, therefore making finding the root cause for such a crash not possible.
Workaround
Disable unattended-upgrades and:
- Rootful: sudo systemctl restart c4_cloud_command on every node
- Rootless: sudo sysctl --system
Fix
Disabled Apport service by default to prevent overwriting of custom core dump pattern.
