csdb rebuild Never Finishes–Database Looping

Database looping is usually caused by corruption in the database files. Since it is a database corruption, it can be unrecoverable. There are several options:

1. Revert to the hot backup.

   If the corruption occurred recently, you can use one of your hot backups.

2. Use your catastrophe archival recovery process.

   For a suggested process, see Restoring an Automatic Backup Copy.

3. Use the dump and reload procedure, Using the Dump and Load Procedure to Recover a Calendar Database.
