pandaPIparser run "Killed"

[rpgoldman]

I was wondering what this means:

$ pandaPIparser repair-domain.hddl repair-problem.hddl
pandaPIparser is configured as follows
  Colors in output: true
  Mode: parsing mode
  Parameter splitting: true
  Conditional effects: exponential encoding
  Disjunctive preconditions as HTN: false
  Replace goal with action: false
  Output: pandaPI format
Killed

Does this represent some kind of resource exhaustion? I don't find the string "Killed" in this repo.
