Reason for continuously increase filesystem size?

Hi
my file system size /hd4 is keep on increasing continuously , i tried all the performance related command to identify which process is currently running........
for every minute my FS(/hd4) size is increasing ?what could be the problem?
how to diagnose it ?

is there any specific command to monitor the file system size?

may be one of ur process is pumping in data to the file system specified continuously

u could check that using the following command

fuser -cu <filesystem>

then u could kill the process swallowing up space

else

directly fuser -k <filesytem> (sends SIGKILL to all the process writing into the filesystem specified)

or

fuser -s <signo> <filesystem>

thanks for ur sugggestion
its a production server.i am not supose to kill any process..........
my intention is to idenfify in which file the size is increasing?

I think that matrixmadhan's suggestion is a bit extreme. You should use

du -sk *|sort -nr|more

to see which file/directory is the largest. If you find the file directly, nothing like it, but you may find that it is a directory, in which case, you have to run the command on that directory, till you find the large file(s).

Then run

fuser -fu <filename>

to see which process is writing to the file(s) and see if you can kill it or not.
