Cannot restart isolated galaxy example

Something seems to be broken when trying to restart SWIFT for running the isolated galaxy example.

As a minimal (hopefully reproducible) example, I use the IsolatedGalaxy/IsolatedGalaxy_feedback example and add the following lines to the isolated_galaxy.yml file:

Restarts:
  delta_hours:        0.03
  max_run_time:       0.08
  onexit:             1
  resubmit_on_exit:   0

When I then run ./run.sh, the simulation times out after the ~56th snapshot, produces the restart file and seems to finish everything properly. Trying to restart the simulations by adding the --restart flag to the swift call in run.sh crashes immediately without any information on what was going wrong.

The (larger) runs that I had submitted to the queue gave the following error message:

/var/slurm/slurmd/job5243086/slurm_script: line 14: 33991 Segmentation fault ./swift --threads=28 --external-gravity --self-gravity --stars --star-formation --cooling --temperature --hydro --feedback --limiter --sync --restart isolated_galaxy.yml

which is also not telling me much. Anyone knows what is going on?

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
