Error restoring nextcloud from backup

[ianhyzy]

I recently moved my cloudron (temporarily) back to a VPS and everything was easy and smooth (thank you for the excellent restore/backup process, cloudron team!) with the exception of Nextcloud. I get "Task Error: Task 3005 crashed with code 255 and signal null" when trying to restore or clone from multiple backups. Any idea on what this is?

@ianhyzy I haven't seen exit code 255 before. Can you paste the last few lines of the app log before it crashes?

@girish this is the last few lines:

@ianhyzy can you go to Backup -> configure and bump up the memory limit (this also affects the memory limit when restoring) ?

[ianhyzy]

@girish I ended up migrating back to my home server a lot faster than I thought and so this is no longer an issue but when I forgot I went from a machine with 32GB of RAM to a VPS with 2 so this was likely it. When I first installed Cloudron is was randomly shutting down and failing to restore becuase it was running out of RAM.
