This problem is reproducible by launching a job then killing the
  slurmstepd process. Under those conditions, requeue the job if
  possible (i.e. batch job with requeue option/configuration).
  This patch also improves the slurmctld logging when this happens.

This is a change in logic from commit 00099596
The original commit corrected the logic from CPU to core count, but
used the cores_per_socket count rather than computing the total
core count (cores_per_socket * sockets).
bug 1830

Continuation of 1bf2d7b9

Correct RebootProgram logic when executed outside of a maintenance
  reservation. Previous logic would mark the node up upon response
  to the reboot RPC (from slurmctld to slurmc) and when the node
  actually rebooted, flag that as an unexpected reboot. This new
  logic checks the node's up time to not mark the compute node as
  being usable until the reboot actually takes place.
but 1866

For testing purposes, add a slurmd flag so that it appears the
compute node has rebooted whenever slurmd restarts.

Save state, even when no buffers are allocated.
Set "last_update_time" on the buffer in some places where it was missing.
Make sure we save state at shutdown.

since this should never happen unless we don't have state files.
