[CentOS] performance problems with OpenLDAP and multiple simultaneous clients
Running CentOS7, with openldap-2.4.40-13.el7. The environment consists of two ldap providers, in mirror mode, serving over a shared virtual IP. Client-facing services are provided by 4 consumers, most of which are accessed over a layer 4 load balancer. Periodically, the consumers encounter some sort of client request(s) which consume all available threads, cause backload threads to spike, and cause slapd to go unresponsive for a long period of time. I've no idea what is causing these events, or if there is anything in the configurations that I can tweak to help. Anyone have any ideas?

[CentOS] SOLVED Re: performance problems with OpenLDAP and multiple simultaneous clients
This turned out to be a blocking issue with rsyslog. So, the slapd issue is solved by uncovering the root cause.
