With seff 18.08.5-2 we have been getting spurious results regarding
memory usage:

  $ seff 1230_27
  Job ID: 1234
  Array Job ID: 1230_27
  Cluster: curta
  User/Group: xxxxxxxxx/xxxxxxxxx
  State: COMPLETED (exit code 0)
  Nodes: 4
  Cores per node: 25
  CPU Utilized: 9-16:49:18
  CPU Efficiency: 30.90% of 31-09:35:00 core-walltime
  Job Wall-clock time: 07:32:09
  Memory Utilized: 48.00 EB (estimated maximum)
  Memory Efficiency: 26388279066.62% of 195.31 GB (1.95 GB/core)

It seems that the more cores are involved the worse the overcalulation
is, but not linearly.

Has anyone else seen this?
