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):

I have removed some log.xxxxx files from /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.
