ORA-01652: unable to extend temp segment by 128 in tablespace TEMP

Question

Hi,
I am getting the following error while executing an insert query.
ORA-01652: unable to extend temp segment by 128 in tablespace TEMP.
I have tried increasing the TEMP tbsp size it got resolved temporarily but occurred again after few days.
When the problem occured, following query shows all insert queries in TEMP tablespace and one of them consumes about 5GB and others are about 24MB.
SELECT S.sid || ',' || S.serial# sid_serial, S.username,
T.blocks * TBS.block_size / 1024 / 1024 mb_used, T.tablespace,
T.sqladdr address, Q.hash_value, Q.sql_text
FROM v$sort_usage T, v$session S, v$sqlarea Q, dba_tablespaces TBS
WHERE T.session_addr = S.saddr
AND T.sqladdr = Q.address (+)
AND T.tablespace = TBS.tablespace_name
ORDER BY S.sid;
The insert query is :
INSERT INTO SEOSDATA (ENTRYID,DOMAINNAME,USERNAME,EVENTTYPE,LOGNAME,TIMSTAMP,SOURCE,COMPUTERNAME,EVENTID,EVENTCATEGORY,SEARCHSTRINGS,MSGTEXT) VALUES (ENTRYID_SEQ.NEXTVAL,:1,:2,:3,:4,:5,:6,:7,:8,:9,:10,:11)
It is not expected that an insert query consumes such a huge memory.
Can someone help me in figuring out what the problem is.
What might have gone wrong? Seems like sorting is used, why an insert query uses sorting?

Hi,
Insert statement should not use TEMP tablespace. Please check with following query which user and session id is using TEMP tablespace.
SELECT b.tablespace, b.segfile#, b.segblk#, b.blocks, a.sid, a.serial#,
a.username, a.osuser, a.status
FROM v$session a,v$sort_usage b
WHERE a.saddr = b.session_addr
ORDER BY b.tablespace, b.segfile#, b.segblk#, b.blocks;
