hello

yes i have verifies before with a "du" if a directory is full in /tmp, but not, just small directory.
I try to work for the script to detect what process use what file, but not easy.. !

no... you're right. a script like that will not be very straight-forward.

what you may wanna do is possibly write a script that will check /tmp filesystem's utilization rather than try and hunt down what process writes what.

after catching a few "large" files being created, you'll have a good idea as to what USUALLY causes the problem.

applications will USUALLY tell you (in documentation) if you need a certain amount of space in /tmp. shoddily programmed ones won't clean them up.

When you use the "rm" command in unix, you unlink a file from a directory. If that was the last link and if the file was not open, the space will be freed. The second condition always catches people. A program opens a large file in /tmp. Someone comes along and "removes" it. Then they wonder why the space was not freed.
