Hey, is it actually crashing or is it just stalling indefinitely?
I ran into duplicati stalling at the start and end of a backup when I initially started testing duplicati. Identified another slow query during backup
I narrowed it down to slow database queries. I identified index’s that fix the issues and got them merged.
Could you share the profiling log on one of the stalled backups? That could let us see if it is a similar issue.
