Error en ldap DB

["Oliver Schulze L." <oliver@samera.com.py>]

Hi,
I'm getting this error when starting my ldap server:
May 29 01:29:51 server slapd[3565]: bdb_db_init: Initializing BDB database
May 29 01:29:51 server slapd[3566]: bdb(dc=example,dc=org,dc=py): 
Program version 4.2 doesn't match environment version
May 29 01:29:51 server slapd[3566]: bdb_db_open: dbenv_open failed: 
Invalid argument (22)
May 29 01:29:51 server slapd[3566]: backend_startup: bi_db_open(0) 
failed! (22)
May 29 01:29:51 server slapd[3566]: bdb(dc=example,dc=org,dc=py): 
txn_checkpoint interface requires an environment configured for the 
transaction subsystem
May 29 01:29:51 server slapd[3566]: bdb_db_destroy: txn_checkpoint 
failed: Invalid argument (22)
May 29 01:29:51 server slapd[3566]: slapd stopped.

I have openldap 2.2.13 running on RedHat EL4. I also have configured
the schemas for working with www.egroupware.org

Later, I deleted the __db.* files and the openldap started, but I don't
know why it stopped working.

I use bdb as my backend.

Many thanks
Oliver
