When running more than just a few simulations (e.g. 10 in parallel), some simulations fail with the error shown in the attached screenshot and this occurs when there are some failed simulations present already. The values therein are 0, the actual free disk space was at least 60 GB at that time.
Workaround: Deleting old, incompleted simulations helped to run new simulations successfully after the same simulations failed when the incompleted simulations were still there.
Expected behaviour: Simulations should always finish successfully – or is temporary disk space of more than 60 GB required? We can provide more details for the used simulations (briefly: Reduced Wong Wang, raw output only, simulation length 1000 ms each).
