What is the current configuration of your
file systems (i.e. df -k)?

I'm assuming if you did not install anything
recently, that something must be writing data
to perhaps log files or something.

Again, it would help to "see" the current
distribution of your file systems.

I did not go through souldier's last post.

from the df -k out put /var nd /opt that comes under root file system there is no separate file systems for this......
that's why root file system is getting full.

I agree - check /tmp and /var for huge temp / log files... I had /var fill up on me once when someone was trying to break in to my home machine - they generated so many log files, that I ran out of room, and it caused me some problems. Since then, I've always made /var a seperate filesystem...

Also, you can try :
du /var > var.du
du /tmp > tmp.du

Now read the var.du and tmp.du files... it will show you where you're using the most space. Look for big numbers, then investigate the directory it's in.
(I think most systems will represent the total size of each directory in kilobytes with du)

Hope this helps.

The general temporary fix when a file system is full is to:

(1) Take a look at the usage with du and look at the top level directories (or second tier) that are the 'big hogs'....

(2) In another file system with plenty of space, copy the entire directory contents over, preserve permissions, etc.

(3) Force a symbolic link between the new directory in the other filesystem to the original offending directory in the problem filesystem.

In this technique, you are moving the troublesome directory and all files to a partition with plenty of space and using a symbolic link to point to the same directory so no system changes are required. This will free up large portions of space (and solve future problems) until you upgrade or add new drives, etc.

Be careful !! Beginners should move files/directories that are not shared libs or other 'more trickly' moves.... and should stick to relocating less tricky directories such as logfiles (that grow quickly!!) and similar files.....
