Thank you for the help. We will look at the clients. I fear sssd would be the culprit, but we have to investigate first. ________________________________ De : Howard Chu <h...@symas.com> Envoyé : lundi 25 mars 2024 20:52 À : Quanah Gibson-Mount <qua...@fast-mail.org>; Christopher Paul <chris.p...@rexconsulting.net>; BECOT Jérôme <jbe...@itsgroup.com>; openldap-technical <openldap-technical@openldap.org> Objet : Re: Help debugging slave slapd issues

Yes, they're common, and these are caused by a client sending too many operations over a connection without waiting for them to complete. In other words, a poorly written client. Simply adding more replicas does nothing to address this, you need a load balancer that spreads all client queries out, even when they're all coming in from a single connection. Better yet is to identify the client and fix it. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
