      What were you trying to do that didn't work?

      The configuration parameter "memberOfDeferredUpdate" was introduced in RHEL 9.6 to improve the LDAP server performance when dealing with large static groups.

      Enabling this parameter is only helpful with Berkeley DB.
      If enabled, it should not be taken into account when using LMDB.

      What is the impact of this issue to you?

      A customer had seen a hang issue while using LMDB and memberOfDeferredUpdate was enabled.

      Please provide the package NVR for which the bug is seen:

       
      grep ^389-ds <SOS_REPORT>/installed-rpms 
      389-ds-base-2.6.1-6.el9_6.x86_64                            Sun May 25 15:39:51 2025
      389-ds-base-libs-2.6.1-6.el9_6.x86_64                       Sun May 25 15:39:44 2025
      

       

      How reproducible is this bug?:

      The hang issue is no longer observed since memberOfDeferredUpdate was disabled on the servers using LMDB. 

      Steps to reproduce

      Was a 1 time event at a customer site.

      Expected results

      No LDAP hang.

      Actual results

      Unresponsive LDAP server.
