Hello, On an already running setup of OpenLDAP 2.4 on Linux (Linux GURKES015 2.6.18-128.el5 #1 SMP Wed Dec 17 11:41:38 EST 2008 x86_64 x86_64 x86_64 GNU/Linux) platform, one day I start
getting following error when I execute the slapcat command: bdb_db_open: warning - no DB_CONFIG file found in directory /opt/proxy/HostedDirectoryLDAPMultiMaster/instances/LdapServers_1/var/openldap-data: (2). Expect poor performance for suffix "dc=ORG,dc=COM".bdb(dc=ORG,dc=COM): Logging region out of memory; you may need to increase its size bdb_db_open: database "dc=ORG,dc=COM": db_open(/opt/proxy/HostedDirectoryLDAPMultiMaster/instances/LdapServers_1/var/openldap-data/id2entry.bdb) failed:

/opt/proxy/HostedDirectoryLDAPMultiMaster/instances/LdapServers_1/var/openldap-data
which are not in use. But still the same error persist while executing slapcat command.
Then I restarted the slapd process. After that I start facing ldaperror 80 with additional info
“index generation failed” error while adding, deleting or modifying any entry along in ldap DB. Could somebody help us to understand: 1.
Why there was “Logging region out of memory; you may need to increase its size”
error. How to resolve it? 2.
Why after slapd restart, I got
“index generation failed” error. How to resolve it? PS: DB_CONFIG was not present in /var/openldap-data directory and slapcat was used to work properly before this issue.
