You could notice that the SYSTEM tablespace is abnormally growing, you try to identify which segments are using most of the space, and you find that the cluster(s) C_TOID_VERSION# and/ or C_OBJ#_INTCOL# is/ are using most of the space.
You can use the below SQL statement to find the top 10 sized segments of the SYSTEM Tablespace:
SQL> col tablespace_name format a20
SQL> select SEGMENT_NAME, SEGMENT_TYPE, TABLESPACE_NAME, MB from
(select segment_name, segment_type, tablespace_name,bytes/1024/1024 MB, rank() over(order by bytes desc) srank from dba_segments) where srank <=10;
