Log miner doesn't show all transactions on a table

Question

I'm playing a little with log miner on oracle 11gR2 on a 32bit CentOS Linux install, but it looks like it's not showing me all DML on my test table. Am I doing something wrong?
Hi, there's my test case:
- Session #1, create table and insert first row:
SQL> create table stolf.test_table (
col1 number,
col2 varchar(10),
col3 varchar(10),
col4 varchar(10));
2 3 4 5
Table created.
SQL> insert into stolf.test_table (col1, col2, col3, col4) values ( 0, 20100305, 0, 0);
1 row created.
SQL> commit;
SQL> select t.ora_rowscn, t.* from stolf.test_table t;
ORA_ROWSCN COL1 COL2 COL3 COL4
1363624 0 20100305 0 0
- Execute shell script to insert a thousand lines into table:
for i in `seq 1 1000`; do
sqlplus -S stolf/<passwd><<-EOF
insert into stolf.test_table (col1, col2, col3, col4) values ( $ , 20100429, ${i}, ${i} );
commit;
EOF
done
- Session #1, switch logfiles:
SQL> alter system switch logfile;
System altered.
SQL> alter system switch logfile;
System altered.
SQL> alter system switch logfile;
System altered.+
- Session #2, start logminer with continuous_mine on, startscn = first row ora_rowscn, endscn=right now. The select on v$logmnr_contents should return at least a thousand rows, but it returns three rows instead :
BEGIN
SYS.DBMS_LOGMNR.START_LOGMNR(STARTSCN=>1363624, ENDSCN=>timestamp_to_scn(sysdate), OPTIONS => sys.DBMS_LOGMNR.DICT_FROM_ONLINE_CATALOG + sys.DBMS_LOGMNR.COMMITTED_DATA_ONLY + SYS.DBMS_LOGMNR.CONTINUOUS_MINE);
END;
