when I used 'db_recover',then:
------------
db_recover: unable to join the environment
db_recover: Ignoring log file: log.0000000020: unsupported log version 8
db_recover: Invalid log file: log.0000000001: Invalid argument
db_recover: PANIC: Invalid argument
and the cursor was blinking
------------
It seemed that 'db_recover' is dead,and openldap can't be start also.
I'm crazying,there are more than 10,000 entries,I can't delete the db.
Can I use 'slapcat' to backup the ldif?
