Is it so large calculations drift ? OK, so your directory sizes aren't changing but you're losing space. It might be that an application is writing to a deleted file (unpacking or streaming to a temporary file, for example). Try running "iotop -a" as root, then use cursors to move the sort column to "DISK WRITE". Leave that running for a few minutes and you'll be able to see which processes are writing the most data.
