It usually ends like this :

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-00601: fatal error in recovery manager
RMAN-03004: fatal error during execution of command
ORA-12170: TNS:Connect timeout occurred
ORACLE error from target database:
ORA-03113: end-of-file on communication channel
