Hi Qu, and thanks a lot for your work. I have a VirtualBox machine (in save-state) with the problem running. So, I can send it to you, if you are comfortable with VirtulBox, or we can work together on my machine. Short story: a) system running is live CD ubuntu 20.04 with kernel 5.4.0-21 b) partition of 10 giga (not /) mounted; c) shrinked to 4 giga; d) then removed files and left just 59 mega of data; e) started balance -m (not -d), then it loops forever (or, at least, I left it running for hours, guess it should be enough). If I reset it, at restart no more loop. Thanks again, Gelma
