based on the timestamp in the ldap.log, it is about 10-15 minutes older than current time. I see a lot of ABANDON msgs which i suspect that there are way too many queries (not ldap connection itself) in a connection. Also, the log shows the constant logs of follwing as well: connection_input: conn=321629 deferring operation: pending operations connection_input: conn=318818 deferring operation: too many executing Looking thru the archive that this is an issue on the client side, and I believe that's true based on the ABANDON msgs on long lasted session ids. I was using logging set to stats, sync . I have changed to none and the symptom of lagging of log timestamp has disappeared and queries are working properly again. My question is, is there a way to safely log stats without hampering performance to the point queries are not returing at all ? I am using openldap-2.4.39 ( yes i should upgrade soon :( ) Thanks
