Encryptfs / Disk Usage Causing System Crash

The problem resides within DUA (disk usage analyzer) but is being caused by the encryptfs virtual file system.

To my understanding it would be logical that DUA reports the encrypted 'home' directory as a different partition ".Private" directory which actually contains all data within the 'Home' directory.

'Home' also reports the exact same amount of usage of disk space.

Now here is the problem.

I am very aware that my disk space is still there, for the mount is virtual. the problem being is that ubuntu and other applications do not feel this to be the same, and it is causing entire system wide destabilization and crashes.

Again its known that disk usage analyzer will report bad disk usage values when dealing with encryptfs and the virtual mount of the .Private and Home folders, but this is cascading across the system and these bad 'values' are causing system crashes slowdowns, etc.

here is some starting Output from DF and DU

After a 12 gig file removal notice no change in disk usage

username01@fake:~$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 139G 120G 12G 91% /
udev 3.9G 4.0K 3.9G 1% /dev

none 3.9G 212K 3.9G 1% /run/shm
/home/username01/.Private 139G 120G 12G 91% /home/username01

Here is some output from DU this will show the virtual double.

username01@fake:~$ sudo du -h --max-depth=1 /home
[sudo] password for username01:
du: cannot access `/home/username01/.gvfs': Permission denied
111G /home/username01
111G /home/.ecryptfs
222G /home

Again lets delete more files and post more output (this time approx 20 gigs from home directory)

DU OUTPUT of everything lets show the 32 gigs did not move to different location....

Ok so after everything we have removed 32 gigs of data.

All viable methods to show disk usage are not returning values of data which has been deleted from partition. The system actually thinks that its file system is full (applications), when infact its not anywhere close to. I am deleting data, and there is no change in any reporting information. and even the reports say there is 9% system disk space left but the system remains unstable to disk space over usage.

Logic being this of expected results from my actions.

If disk space is reported as 'doubled'
If i remove 32 gigs of data
would that not dictate that 64 gigs of data were removed, why is 0 gain reported back on all utilities?

OR

If i remove 32 gigs of data would that not dictate at MINIMUM 32 gig increase in usable space, even though deleted files are not residing in recycle bin, etc....

Also one might note that why am I getting system crashes due to over usage in disk space when i still have disk space left to utilize even if its reported as 'doubled'...
