For the rest: The issue is that there are a large number of files (> 400k) getting backed up and the syncer code is running out of memory since it loads all those filenames in memory. I will get this fixed in the next version. For now, disable automatic backups for nextcloud.

After editing the file, you have to run:

systemctl daemon-reload
systemctl restart box

Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

Is there error here. I am not sure of a fix, but hope it helps you find one.
