What is RRV bucket error?

In case "fixup -f", then "compact -c -i" utilities do not work for your Lotus Notes database file, you can try a third party Lotus Notes recovery software to repair and recover data from severely damaged Lotus Notes database. One such globally used application that I know is Stellar Phoenix Lotus Notes Recovery.

The Record Relocation Vector (RRV) is a table that points to the notes within the database. Depending on the problem with the RRV, Domino can attempt to recover the information to rebuild the RRV when using the compact -c command or creating a new replica of the database.

 
if the maintenance tools have failed and the database cannot be opened to create a new replica, it means the RRV table is badly damaged enough that the table is unrecoverable. At that time, the only option is to restore the file from backup.

Even do not have any solution to fix RRV bucket error.

The error "RRV bucket is corrupt" can't be repaired. RRV bucket means "Record Relocation Vector" table, and if this is damaged, then it can't be repaired. Fixup, compact, updall and replace design all will fail and will throw the same error. The only solution is to replace with the last back up copy of database. RRV bucket becomes corrupt if the OS hangs, crashes or restarted at the moment when the Record Relocation Vector table is being updated.

Actually and RRV bucket error happens when you are opening the mail. An RRV bucket contains the information to locate the data for specific notes or object identifiers within a database. This error indicates that the information is corrupt. Whenever possible, the database should be restored from a backup or a new replica pulled from a good copy of the database. If that is not possible, some data might be salvaged by running "fixup -f", then "compact -c -i" on the database.
