Open ldap master slave replication not properly syncing

Hi guys ,

i have master slave LDAP replication setup , where master have close to 38000 records, when i start the slave server its starts syncing from master , but when the sync finished slave only sync records close to 30000,. is there any reson for this.

please note that ,

and in slave slapd.conf file it has entry "sizelimit 55000" both the servers have identical times: and in the slave log file i can see the "do_syncrep2: rid=004 CSN too old, ignoring" entry.

is there any way sort this issue.

Thank You Dhanushka
