You might want to include the -x flag for du to ensure that you don't read any sub-mounted filesystems.

Find files younger than 7 days and bigger than 10 blocks, and sort by size; stay on the /u01 file system:

Code:

find /u01 -xdev -type f -mtime -7 -size +10 -ls | sort -k7n

You should check to see if tracing is turned on in the database. Of the directories that you show, which directory has the diag directory and how large is the .../diag/rdbms/<sidname>/<sidname>/trace directory. If that is the directory that is growing, then you need to turn off tracing and clean up the old trace files. Another option would be if either the temp or undo table spaces can grow without limit. If so you should check the size of your temp and undo directories to see if they are way too large. Ultimately, this looks like a database issue.

Careful about deleting database files, unless you really want to practice your database recovery strategy. ;-)
