check_swatinit has been observed to get killed by the Linux OOM-killer implying that it used a lot of memory.

The maximal amount seen is 120Gb, which is a lot. A typical compute node has 12Gb of RAM available pr processors.

Most likely run on a model with a large number of cells.

The script should be checked for:

  • Keeping (almost?) duplicates of dataframes in memory simultaneously, maybe some operations can be done in-place?
  • Unneeded columns kept in dataframes.
  • Check for inactive cells, if so, can they be purged?
