A few days ago, I received the following warning message: "Too little diskspace forcing PAUSE". I checked this of course, and noticed that I have about 10% free on my destination drive. My problem with this, is that I am using a (roughly) 6TB destination drive, so I had about 600GB free, which is quite sufficient for my (at that time) queue.
I don't think the warning came for my temporary/work directory, as I had about 60GB free there, and my queue was less than that. (My settings say to pause at 2GB free there)
Is the 10% (or something simular) hardcoded? Or is it a setting (that I can't find)? Or is something else up?
All in all there was no real issue, as I could just unpause it, and SAB continued nicely of course :-)
