Oracle Enterprise edition
Solaris 2.8

I use RMAN to do backups of my databases.The catalog is installed on a separate server .
i have a problem with RMAN BACKUP on a new server, at the end of the backup RMAN is not able to resync the catalog (see error message), i think RMAN lose the connection to the catalog before finishing the backup.
This problem happen sometimes not all the time.sometimes it works fine and RMAN finishes the backupwithout errors.

Any help is appreciated,

Here is the error message
