In fact, I have the same problem about running low on space, whereas it is not the case.
And disk_min_free_space is already set to 0 in my configuration. But I don't find any disk_check_free_space in the settings.
Had the same issue with my WD Mycloud EX4100. I tried to reinstall the bin found on Resilio site (2.7.2.1375) today... and it seems to install! Thanx for the job! 🙂
