One of the ways to find out what has the largest files open is # fstat | grep /var | sort -r -n -k 8 | head (gives you the `top ten list' of the largest open files and the processes which use them). If the problem is in a program holding lots of small files open, then a different script (utilizing uniq -c) could be devised. > If you are doing database stuff, then I can't imagine having a /var > of less than a few GB, unless you move a lot of stuff out of /var and > create links.
