My Nagios system sent me an alert to inform me that the disk space on one of the drives on our OS X server is very low. When I run df /Volumes/Apps/ I get

/dev/disk0s3  117209520 114932472   2277048    99%    /Volumes/Apps

When I run du -c /Volumes/Apps it reports

11489944        total

Why might there be such a vast difference? Even more importantly, how do I find the problem and what can I do about it? I'm essentially just a Windows admin, so am well out of my comfort zone here. I use a Mac but I'm not a Mac admin in any real sense of the word.
