System Drive keeps filling up to capacity!

[Bob Douglas]

I am hoping someone can help me with a serious problem I am having with my OS 10.2.4 system drive partition. For no apparent reason the drive keeps filling up until there is no more space available on the drive. I have tried everything I know to fix this, to no avail: I have run Permissions, Run Repair, reboot and run "Single user mode", Disk Warrior, and more. I emptied all the caches, I disconnected the network, I re-installed the image from a previous "Carbon Copy Clone", and still I get this symptom. You can actually click on the disk info every few minutes and see less and less space, until it's all gone.
I even checked the size of each folder individually to see if I could find where this mysterious data is being stored. My results were that all the folder sizes remained the same and added up to their original size. If anyone has any suggestions or could help me with this I would really appreciate it!

Thank you for your time in advance,
Bob Douglas

command line it

sudo -s (for a root prompt)
cd /
du -sk *
du -sk *

keep issuing du -sk until you see what's growing. As a normal user you don't have permission to see all the files; as root, you should. If you find which folder it is, cd into that folder, and issue du -sk * again.

I'd also check top or process viewer to see if anything is being a general resource hog. It's hard for me to believe that comething is writing to disk without using the CPU too. :-)
