   Not quite -- I was some 5G free on a 50G filesystem, without
errors. I expanded the filesystem online to 70G because I knew I would
run out within the next few hours. Despite the expansion, it still ran
out at (just short of) 50G.

   Unless you've resized your filesystem online, I think we're seeing
different problems.
