Hi,

I have multimaster replication environment. On each replica, folder 
/var/lib/dirsrv/slapd-xxxx/cldb/ has big size (3~GB) and old entries in 
/var/lib/dirsrv/slapd-xxx/cldb/xxx.db4 have three month year old:

sudo dbscan -f 
/var/lib/dirsrv/slapd-xxxx/cldb/ef155b03-dda611e2-a156db20-90xxx06_51c9aed900xxxxxx000.db4

My questions are:

a) How to purge old entries in file /var/lib/dirsrv/slapd-xxx/cldb/xxx.db4? 
(what is the procedure)
b) What is the right configuration to limit increase of this file?



This topic has been already talk on 
https://www.redhat.com/archives/freeipa-users/2013-February/msg00433.html or 
https://www.redhat.com/archives/freeipa-users/2015-April/msg00573.html but no 
response work for me.
Response here seems to be not applicable 
https://bugzilla.redhat.com/show_bug.cgi?id=1181341 (Centos 7, Fixed In 
Version: 389-ds-base-1.3.4.0-1.el7)

I used some attributes from the docuementation: 
https://access.redhat.com/documentation/en-US/Red_Hat_Directory_Server/9.0/html/Configuration_Command_and_File_Reference/Core_Server_Configuration_Reference.html#cnchangelog5-nsslapd_changelogdir.
 Old entries are not purged and file increase even after restart service 
(service dirvsrv start and service dirvsrv stop).

(This test environment values)
dn: cn=changelog5,cn=config
objectClass: top
objectClass: extensibleobject
cn: changelog5

nsslapd-changelogmaxentries: 100
nsslapd-changelogmaxage: 4m

Hereafter some informations about my environment: 
CentOS release 6.5 (Final)
389-ds-base-libs-1.2.11.15-65.el6_7.x86_64

Thanks for your help!
