Hi, Thanks for the following information. Can you please provide your input for the following queries below:
•Is database cache is all that I have to take care off only? •How to decide the value of ‘set_lg_regionmax’ parameter? •For below problem should I need to increase the value of DB cache size or ‘set_lg_regionmax’ if the issue occurs again. • Is the ‘index generation failed’ issue linked to the logging region issue?

This should be configured in a DB_CONFIG file within the database directory. Your OS distribution may have provided a sample DB_CONFIG file. > > 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. The referenced log files document the database transactions and are vital for database operations. You may read on db_config tools and how to manage transaction logs.
