This will run a while, but will show you a path for each directory, it chops off the list with the 20 largest directories. By largest I mean how much space the directory uses, this includes subdirectories. So with one subdirectory using lots of space each of the parent directories of the biggie will also show up in the list. Hence look for more than just one, I guessed 20, so one of them will likely be the bad guy directory itself.
If you are having problems with processes silently using space, consider implementing quotas on file systems you need to protect. Also, consider NOT having "ordinary applications" access to writable directories on the / FS. Put the directories somewhere else.

switch_root
SWITCH_ROOT(8) System Administration SWITCH_ROOT(8)NAME
switch_root - switch to another filesystem as the root of the mount tree
SYNOPSIS
switch_root [-hV]
switch_root newroot init [arg...]
DESCRIPTION
switch_root moves already mounted /proc, /dev, /sys and /run to newroot and makes newroot the new root filesystem and starts init process.
WARNING: switch_root removes recursively all files and directories on the current root filesystem.
OPTIONS -h, --help
Display help text and exit.
-V, --version
Display version information and exit.
RETURN VALUE
switch_root returns 0 on success and 1 on failure.
NOTES
switch_root will fail to function if newroot is not the root of a mount. If you want to switch root into a directory that does not meet
this requirement then you can first use a bind-mounting trick to turn any directory into a mount point:
mount --bind $DIR $DIR
