["Sergio Belkin" <sebelk@gmail.com>]

I have a problem trying to recover ldap database, error are as follow:

slapd_db_recover -h /var/lib/ldap/ -c -v
Finding last valid log LSN: file: 1 offset 729642
Recovery starting from [1][28]
db_recover: Improper file close at 1/623901
db_recover: Recovery function for LSN 1 623901 failed on forward pass
db_recover: PANIC: Invalid argument
db_recover: PANIC: fatal region error detected; run recovery
db_recover: DB_ENV->open: DB_RUNRECOVERY: Fatal error, run database recovery


How can I recover it?

Thanks in advance!
