As discussed in previous messages in this thread, here is a patch to SLURM
2.3.1 "src/slurmctld/controller.c" to eliminate the SlurmctldLogFile path
as the location of the core file dump and just set the location to the
SlurmStateSave directory, if slurmctld is running as a daemon. The patch
should also apply to SLURM 2.4.0 (with a one-line relocation).

And here is a patch for the "doc/man/man8/slurmctld.8" man page to
document the change. It should apply to both 2.3.1 and 2.4.0.

.SH "CORE FILE LOCATION"
If slurmctld is started with the \fB\-D\fR option then the core file will
be
written to the current working directory.
-Otherwise if \fBSlurmctldLogFile\fR is a fully qualified path name
(starting
-with a slash), the core file will be written to the same directory as the
-log file.
Otherwise the core file will be written to the \fBStateSaveLocation\fR.
+SlurmUser must have permission to create files in the
\fBStateSaveLocation\fR
+directory for a core file to be produced.
The command "scontrol abort" can be used to abort the slurmctld daemon
and
generate a core file.
Tested on both 2.3.1 and 2.4.0-rc3.
