RMAN script doesnt exit shell after backup

Question

Hi,
I've the following script on AIX 6.1, Oracle 11.2.0.1.0:
export ORACLE_HOME=/oracle/medprod/product/11.2.0/dbhome_1
export ORACLE_SID=MEDPROD
export PATH=$ORACLE_HOME/bin:$PATH
export LOG_DIR=/home/medinous/backup/logs
export LOG_FILE=$LOG_DIR/medprod_daily_backup_`date +%d%m%Y%X`.log
rman target / catalog rman/rman@rman log=$LOG_FILE <<EOF
execute script medinous_daily;
exit;
EXIT;
EOF
and:
printing stored script: medinous_daily
+{+
allocate channel t1 type 'sbt_tape' parms 'ENV=(TDPO_OPTFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.opt)';
allocate channel t2 type 'sbt_tape' parms 'ENV=(TDPO_OPTFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.opt)';
allocate channel t3 type 'sbt_tape' parms 'ENV=(TDPO_OPTFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.opt)';
backup format 'medinous_dailybackup_%d_%s_%t'  database;
backup  format 'medinous_dailyarchbackup_%d_%s_%t' archivelog all not backed up 1 times;
crosscheck backup;
delete noprompt obsolete;
delete noprompt expired backup;
delete noprompt expired archivelog all;
release channel t1;
release channel t2;
release channel t3;
+}+
For some reason, the rman script, scheduled via crontab doesn't exit after successful backup, the process just remain alive, even though there's an explicit exit command at the end.
Any idea?

No, the script actully executes successfully. The problem is that after executing, the process does'nt die, it doesnt exit rman:
