Replication failling and not retrieving all entries

["Gustavo Lima" <gustavopml@gmail.com>]

Hi All,

 

I have a big network with one master openldap 2.3.30 running on Debian Etch fully updated.

 

I have other 27 consumers using replication on refresAndPersist type working 100% fine with one exception.

 

This exception have the same configurations off all other servers. I have already changed the WAN provider (it was planned to change it), the switch where the server is connected, network cable, the hole server and nothing seems to change the strange behavior.

 

What happens is this specific machine does not receive all the 8323 objects from the master. On debug mode it does not show any error. The openldap simply thinks the replica have finished. Then some seconds later it start replicating again but not from the stop point. The best that I have is 5217 objects replicated.

 

My conf on this server was copied from another working installation and then changed the "rid".

 

This is how my conf is:

When the replication stops the log just shows:

Dec  8 15:55:09 mg slapd[6529]: syncrepl_entry: LDAP_RES_SEARCH_ENTRY(LDAP_SYNC_ADD)

Dec  8 15:55:09 mg slapd[6529]: bdb_idl_fetch_key: [7cdee34d]

Dec  8 15:55:09 mg slapd[6529]: connection_get(39)

Note that the first line is saying LDAP_SYNC_ADD and not LDAP_SYNC_MODIFY once this user is already loaded.

Anyone can help us with this one?

Thanx in advance.
