Symptoms

In Oracle Database 11gR1 and 11gR2:

One may find a large number of OS audit trail files, ending in .aud, being generated on the filesystem in AUDIT_FILE_DEST.

These files can be very small: less than 1KB in size. 

The names of these files often share an OS PID number, such as:

rdbms_ora_663_1.aud
rdbms_ora_663_2.aud
rdbms_ora_663_3.aud 

What are possible reasons for these files being created with such frequency?
