I would suspect that /var, and possibly /tmp are filling up with 
temporary files, if these are not on separate partitions. Mail spool 
files, if there are enough of them, could eat a big chunk out 
of /var. (I suspect this is what Donald Teed was thinking about in 
his comment.)

stat -f -c \%f /


df -H /

can be used to discover the amount of *free* space on the root 
partition. This could be incorporated into a script, along with du -s 
commands to look at the sizes of specific suspect directories. Run 
frequently as a cron job you could get an idea of the space 
utilization over time.
