I have configured three openldap servers(2 Masters and 1 Slave). I have configure PEN load balancer for failover setup on 2 master openldap servers.It means application server first of all hit the loadbalancer port and than PEN LB will forwad that request to Master 1 or 2 openldap server. Hardware configuration on all boxes: OS: RHEL5(x86_64) RAM: 2GB Number of CPU: 2(Intel(R) Xeon(R)2.00GHz) Number of BDB databases: 2 Databse1: Number of users : 830000 Number of dns: 830000 Database2: Number of users: 2000 Number of dns: 800000 My Application1 using Databse1 and Application2 using Databse2. Application2 just authenticating the users and store last 10 password history only, It means Application1 is not using openldap too much. In Application2(90% dependent on openldap) every user have 1000+ sub leafs entries. when I want to do major changes(number of leafs write) into this, it.s got hanged and got socket closed error in application logs and CPU utilization goes 200% and RAM 52%. My DB_CONFIG file is below: # $OpenLDAP: pkg/ldap/servers/slapd/DB_CONFIG,v 1.3.2.4 2007/12/18 11:53:27 ghenry Exp $ # Example DB_CONFIG file for use with slapd(8) BDB/HDB databases. # # See the Oracle Berkeley DB documentation # <http://www.oracle.com/technology/documentation/berkeley-db/db/ref/env/db_config.html> # for detail description of DB_CONFIG syntax and semantics. # # Hints can also be found in the OpenLDAP Software FAQ # <http://www.openldap.org/faq/index.cgi?file=2> # in particular: # <http://www.openldap.org/faq/index.cgi?file=1075> # Note: most DB_CONFIG settings will take effect only upon rebuilding # the DB environment. # one 0.25 GB cache set_cachesize 0 268435456 1 # Data Directory #set_data_dir db # Transaction Log settings set_lg_regionmax 262144 set_lg_bsize 2097152 #set_lg_dir logs # Note: special DB_CONFIG flags are no longer needed for "quick" # slapadd(8) or slapindex(8) access (see their -q option).
