Greetings to all. after a power failure the Zimbra 7.0.1 won't start:

Starting ldap...Done.
Failed to start slapd. Attempting debug start to determine error.
bdb(cn=accesslog): PANIC: fatal region error detected; run recovery
bdb_db_close: database "cn=accesslog": txn_checkpoint failed: Invalid argument (22).
backend_startup_one (type=hdb, suffix="cn=accesslog"): bi_db_open failed! (-30974)
bdb_db_close: database "cn=accesslog": alock_close failed

Is there a solution?
