It is possible for a process to have a file open that doesn't have a directory entry. This can happen when a process opens a file, unlinks it, and continues to write to it. You can use the fstat utility to see what processes have files open on a file system. E.g. $ fstat -f /tmp This won't tell you how big those unlinked files are, but it will give you a list of suspects. You can restart them and see which one releases the space. - todd
