Your Question , its not clear, no such things like release space under / root file system

by execution of the above command shown previous post will help shed light on your Question or problem,

>>Root FS getting full<< ?

there could be many reasons for above Questions

does any of your application "logs, data" pointed to write to / root file system ..?

due have any core file created ..?

[Johnson Punniyalingam]

Yes, you can only OLD.rc.log

what is your OS version ?

[Patrick Wallek · Accepted solution]

One of the first things I look for in the '/' file system is a "real" file in the /dev directory.

Do this:

# cd /dev
# find . -type f | xargs ls -l

If this returns anything then examine it closely. There should be nothing other than device files in the /dev directory structure.

pls start checking As advices, >>Patrick Wallek <<<

# cd /
# du -sk *
