Is it possible to provide the custom schema you are using, and an example of a user entry you are loading, so I can template it? I'd like to see if I can reproduce the problem.

Hello Quanah, I added the syncprov overlay to the 1st database, but is neither used by our application (rather than by another off-the-shelf application) nor replicated as is for the 2nd database. For your 2nd request, unfortunately I'm not able to test it, since between the LDAP and my test-bench application there is another server side application: Test-bench_application --> spring_http_invoker --> Server_side_app ---> data_for_db_2 ---> LDAP ---> data_from_db_2 ---> App_in_syncprov_with_ldap I don't have the control over the section "server_side_app ---> data_for_db_2 ---> LDAP". Anyway, as said above, now I enabled the syncprov over both databases: --- begin slapd.conf --- database bdb suffix "o=3Dorgname,c=3Dat" checkpoint 1024 15 rootdn "cn=3Droot,o=3Dorgname,c=3Dat" rootpw XYZ directory /var/lib/ldap index entryCSN eq index entryUUID eq overlay syncprov syncprov-checkpoint 1000 10 syncprov-sessionlog 1000 syncprov-reloadhint TRUE syncprov-nopresent FALSE database bdb suffix "o=3Dvivates,c=3Dch" checkpoint 1024 15 rootdn "cn=3Droot,o=3Dvivates,c=3Dch" rootpw XXX directory /var/lib/ldap-hpd index entryCSN eq index entryUUID eq overlay unique unique_attributes hcIdentifier overlay syncprov syncprov-checkpoint 1000 10 syncprov-sessionlog 1000 syncprov-reloadhint TRUE syncprov-nopresent FALSE --- end slapd.conf --- but unfortunately I had the same issue (as usual, I restarted the server before debugging SLAPD). Please note: if I keep stopped the application that is in syncprov with LDAP ("App_in_syncprov_with_ldap" on the schema above), I load all the entries in the 2nd database, then I turn that application on, then slapd works flawless and the (offline) synchronization is done right. --- begin gdb session --- top - 08:56:12 up 4 min, 2 users, load average: 0.09, 0.27, 0.14 Tasks: 124 total, 1 running, 123 sleeping, 0 stopped, 0 zombie Cpu(s): 0.5%us, 0.5%sy, 0.0%ni, 99.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0= %st Mem: 4019472k total, 2928668k used, 1090804k free, 56080k buffers Swap: 2064380k total, 0k used, 2064380k free, 1572400k cached [root@ibb0301 .libs]# pwd /root/src_openldap/openldap/servers/slapd/.libs [root@ibb0301 .libs]# ./slapd -VVV @(#) $OpenLDAP: slapd 2.4.X (Oct 30 2015 08:49:20) $ root@ibb0301:/root/src_openldap/openldap/servers/slapd Included static overlays: syncprov Included static backends: config ldif monitor bdb hdb ldap mdb relay [root@ibb0301 .libs]# gdb ./slapd GNU gdb (GDB) Red Hat Enterprise Linux (7.2-83.el6) Copyright (C) 2010 Free Software Foundation, Inc.

Also, if you make it a single DB (using a suffix of "") rather than two distinct DBs, do you still hit the issue? --Quanah -- Quanah Gibson-Mount Platform Architect Zimbra, Inc. -------------------- Zimbra :: the leader in open source messaging and collaboration

Hello Quanah, thanks for the hint. I cloned the repository and checked out the branch you told me: [root@ibb0301 openldap]# git checkout OPENLDAP_REL_ENG_2_4 Already on 'OPENLDAP_REL_ENG_2_4' [root@ibb0301 openldap]# git branch * OPENLDAP_REL_ENG_2_4 master Then, after compiling the whole stuff, I started it as usual with GDB and with my client application active (synch via syncprov). Here again I got a failure due to failed malloc (returns NULL). As that moment, the %MEM shown by top was about 66% (it increased till here up to 1% every 10s). Please consider that, before starting gdb, I rebooted my server (4 GB RAM, 2 GB swap) This is the GDB trace: --- begin gdb --- root@ibb0301 .libs]# pwd /root/src_openldap/openldap/servers/slapd/.libs [root@ibb0301 .libs]# ./slapd -VVV @(#) $OpenLDAP: slapd 2.4.X (Oct 29 2015 09:45:56) $ root@ibb0301:/root/src_openldap/openldap/servers/slapd Included static overlays: syncprov Included static backends: config ldif monitor bdb hdb ldap mdb relay [root@ibb0301 .libs]# gdb ./slapd GNU gdb (GDB) Red Hat Enterprise Linux (7.2-83.el6) Copyright (C) 2010 Free Software Foundation, Inc.
