coredumpctl is unable to retrieve a coredump from the journal

This document (7023161) is provided subject to the disclaimer at the end of this document.


SUSE Linux Enterprise Server 12 Service Pack 3 (SLES 12 SP3)


When attempting to retrieve a systemd service coredump from the journal, this fails with:

Cannot retrieve coredump from journal nor disk.
Coredump retrieval failed: No such file or directory


For the service that is dumping core, follow the steps as described in the SUSE Linux Enterprise Server Administration Guide to customize or create a "Drop-in" file for a systemd service.  The following needs to be added:


Alternatively to globally change the setting for all services, un-remark the "DefaultLimitCORE=infinity" setting in "/etc/systemd/system.conf"

After either of the above changes it is needed to restart the relevant systemd service(s).

It is also needed to set the following:

sysctl -w kernel.suid_dumpable=2


The "Soft Limit" for the "Max core file size" of systemd services by default is set to 0, which prevents the writing of core files.

Additional Information

For general information on how to use coredumpctl see TID 7017137 - How to obtain systemd service core dumps.

To verify the current limit(s) is in effect for a service, run:

:~ # cat /proc/$(pidof <insert_service_name>)/limits
