I also suggested that a couple of days ago. It is important to check the 
root user's home directory as well as your standard home directory.

If its only 170 kB, then it's not the problem you're looking for. The 
scenario I was referring to is when you get thousands of X errors a 
second, and the .xsession-errors file explodes out to hundreds of 
megabytes or gigabytes in size.

Here's a thought... if you disconnect the internet, does the root 
partition stop filling up? Give it, say, 10 minutes and see if it stops 
growing, and then starts again when you turn the connection back on.

Does your ISP offer usage stats? If so, are they unusual?

My thinking is to discover whether or not this unusual disk usage is 
purely internal, or whether it has something to do with the internet 
access: either data being downloaded, or uploaded, or both.

Not necessarily something malicious. Maybe you've got a rogue 
(misconfigured) program downloading updates over and over and over 
again, thousands of times.
