Riddle me on this one

[William Muriithi]

Morning

I have a system that is maxing up the disk space and was trying to
find a logs to purge.  The odd thing is, the root of the log directory
reports 3.6G, but all the logs file living on that directory do not
even come close to the sum of all the logs file size added up.

du -h /var/log
4.0K	/var/log/unattended-upgrades
4.0K	/var/log/apparmor
4.0K	/var/log/landscape
4.0K	/var/log/dist-upgrade
56K	/var/log/apt
40K	/var/log/ConsoleKit
824K	/var/log/exim4
4.0K	/var/log/news
4.0K	/var/log/jetty
12K	/var/log/fsck
3.6G	/var/log

Why would that happen?  How would I fix it?  Someone seem this before?
 Really odd, or I am missing something fundamental

Thanks in advance and great weekend

William
