Dear Sir/ Madam,

We are having two OpenLDAP servers on production with master master data synchronization. We are facing an incident where both servers consume memory upto 99% and LDAP server2 leads to not responding state.

As a workaround we have restart both OpenLDAP nodes. However after few days the memory goes high at its peak.

There are about 100k+ requests for one LDAP server per day. where both servers are identical in terms of 16 GB RAM, 4 CPUs, CentOS7 OS and LDAP server 2.4.44. We didnt observe any suspiciuos errors in the logs as well.

Appreciate your valued consultation and recomendations on this incident for a RCA and a solution.

Thank You

Regards, Gihan.
