I’ve noticed this error/warning that keeps standing out when starting slapd on ldapserver2: slapd: search.c:1125: oc_filter: Assertion `f != ((void *)0)' failed. In my google searches I found this post from Quanah as a possible bug in 2.4.44 (we’re running 2.4.40): This list is for discussing reported issues in OpenLDAP Software () headers quanah | 27 Apr 16:56 2016 (ITS#8413) Assertion in back-mdb/search.c during replication Full_Name: Quanah Gibson-Mount Version: 2.4.44 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (75.111.52.177) During replication from the accesslog DB, in a 4-way MMR setup, various masters periodically crash with slapd: search.c:1246: oc_filter: Assertion `f != ((void *)0)' failed. This is back-mdb/search.c, not slapd-search.c This is triggered when a NULL filter is passed through. However, it should be impossible for the filter generated by str2filter to ever fail.

Borresen (Dave) Email: john.borresen@ll.mit.edu From: openldap-technical [mailto:openldap-technical-bounces@openldap.org] On Behalf Of Borresen, John - 0444 - MITLL We have a 3-way multimaster configuration running on CentOS 5.11, OpenLDAP 2.4.40. All three have been up for years, until the other day: Slapd is running on two of the three (server names: ldapserver1, ldapserver2, and ldapserver3). Slapd stopped and won’t restart on ldapserver2.
