Public bug reported: I am running several I/O intensive applications creating and deleting many files on the separate /home partition. After about a day of operation my root file system / containing everything except /home goes 100% full, although running ncdu -x from / shows just about 50% fullness. 100% goes down to (correct) 52% after a reboot. Note that all my files are created within the mounted /home partition. I do not run any specific process as a root (beyond those of a stock Ubuntu 14.04 distribution).
