I guess It depends how large your dataset is, some peoples run urbackup at home ona raspberry pi or their nas
You get that much like within 24h of a service restart? Since when is the application started ?
In advanced tab, what did you set for "Database cache size during batch processing:"
Can you show the memory usage, as you see it ?
From the windows task manager (detailled view, click column tittle, check memry related columns) or better the detail view from the pstools process explorer.
Or on linux cat /proc/pidofurbackup/status
Also if possible, please dont restart the service right now, maybe uroni will like you to run memleax on the process.
For info , this is what i get with a few tb of backups, and cache size set to 1gb for batch.
