Hello,
We are using openldap2.3, BDB 4.5.20 and Rehat3..seeing having high cpu usage of the slapd process.
Tried with bellow indexes, we can't use "cachesize" as we have nightly restart of the process and cache go away (let me know there is way to save cache and it will be available even after restart of slapd); also we have yearly onetime users in our system.
Please let me know what are can be done to solve slapd high cpu utilization problem.
