Is there an update to this issue? I just got started and paid for Cloudberry backup and having the same issue as John. I'm running the latest 2.9.2.14 version and backing up to B2. It seems to be related to thread count, as I was able to get a normal backup exit by setting the number of threads to 1. It's just slower in this case, and overnight backups are going to take a month at this point to complete.
