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.

--001a1130d27c49538c05232c9dd4 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable I cloned the git repository "git://git.openldap.org/openldap.git", then I compiled this version "2.X" as specified in the 1st message. Please consider that, after recompiling this version, I rebooted the server where slapd is running. As far as I can see, it seems the memory consumption is the same as 2.4.42: it starts to increase up to 60%. In fact, with gdb, I got now an assertion failed due to: ---- 5630f547 connection_get(22): got connid=3D1001 5630f547 connection_read(22): checking for input on id=3D1001 ber_get_next ber_get_next: tag 0x30 len 188 contents: 5630f547 op tag 0x66, time 1446049095 ber_get_next 5630f547 conn=3D1001 op=3D46535 do_modify ber_scanf fmt ({m) ber: ber_scanf fmt ({e{m[W]}}) ber: 5630f547 =3D> get_ctrls ber_scanf fmt ({m) ber: 5630f547 =3D> get_ctrls: oid=3D"2.16.840.1.113730.3.4.2" (noncritical) 5630f547 <=3D get_ctrls: n=3D1 rc=3D0 err=3D"" 5630f547 >>> dnPrettyNormal: <cn=3D1000000000000_O2HP,ou=3DRelationship,dc=3DHPD,o=3Dvivates,c=3Dch> 5630f547 <<< dnPrettyNormal: <cn=3D1000000000000_O2HP,ou=3DRelationship,dc=3DHPD,o=3Dvivates,c=3Dch>, <cn=3D1000000000000_o2hp,ou=3Drelationship,dc=3Dhpd,o=3Dvivates,c=3Dch> 5630f547 >>> dnPretty: <cn=3DSimon Cottet.7601000061447,ou=3DHCProfessional,dc=3DHPD,o=3Dvivates,c=3Dch> 5630f547 <<< dnPretty: <cn=3DSimon Cottet.7601000061447,ou=3DHCProfessional,dc=3DHPD,o=3Dvivates,c=3Dch> 5630f547 >>> dnNormalize: <cn=3DSimon Cottet.7601000061447,ou=3DHCProfessional,dc=3DHPD,o=3Dvivates,c=3Dch> 5630f547 <<< dnNormalize: <cn=3Dsimon cottet.7601000061447,ou=3Dhcprofessional,dc=3Dhpd,o=3Dvivates,c=3Dch> 5630f547 bdb_dn2entry("cn=3D1000000000000_o2hp,ou=3Drelationship,dc=3Dhpd,o=3Dvivate= s,c=3Dch") 5630f547 bdb_entry_get: rc=3D0 5630f547 syncprov_matchops: sid ffffffff fscope 1 rc 6 5630f547 =3D=3D> unique_modify <cn=3D1000000000000_O2HP,ou=3DRelationship,dc=3DHPD,o=3Dvivates,c=3Dch> 5630f547 bdb_dn2entry("cn=3D1000000000000_o2hp,ou=3Drelationship,dc=3Dhpd,o=3Dvivate= s,c=3Dch") 5630f547 bdb_entry_get: rc=3D0 5630f547 unique_modify: administrative bypass, skipping 5630f547 bdb_modify: txn1 id: 80005c1f 5630f547 bdb_dn2entry("cn=3D1000000000000_o2hp,ou=3Drelationship,dc=3Dhpd,o=3Dvivate= s,c=3Dch") 5630f547 bdb_modify: txn2 id: 80005c20 5630f547 bdb_modify_internal: 0x00000288: cn=3D1000000000000_O2HP,ou=3DRelationship,dc=3DHPD,o=3Dvivates,c=3Dch 5630f547 oc_check_required entry (cn=3D1000000000000_O2HP,ou=3DRelationship,dc=3DHPD,o=3Dvivates,c=3Dch), ob= jectClass "VivatesHCRelationship" 5630f547 oc_check_allowed type "relationshipType" 5630f547 oc_check_allowed type "owner" 5630f547 oc_check_allowed type "objectClass" 5630f547 oc_check_allowed type "cn" 5630f547 oc_check_allowed type "member" 5630f547 oc_check_allowed type "structuralObjectClass" 5630f547 oc_check_allowed type "entryUUID" 5630f547 oc_check_allowed type "creatorsName" 5630f547 oc_check_allowed type "createTimestamp" 5630f547 oc_check_allowed type "entryCSN" 5630f547 oc_check_allowed type "modifiersName" 5630f547 oc_check_allowed type "modifyTimestamp" 5630f547 =3D> key_change(DELETE,288) 5630f547 <=3D key_change 0 5630f547 =3D> key_change(ADD,288) 5630f547 <=3D key_change 0 5630f547 =3D> entry_encode(0x00000288): cn=3D1000000000000_O2HP,ou=3DRelationship,dc=3DHPD,o=3Dvivates,c=3Dch 5630f547 ch_malloc of 837196 bytes failed slapd: ch_malloc.c:57: ch_malloc: Assertion `0' failed.

I may have misread your message. If the same binary works on a newer system, that tends to imply something weird in the runtime environment.

I ran a test on one machine and got an abort in glibc saying there was a stack overrun. On a different machine I got no such error, and running on the problem system under valgrind produced no errors. On the machine that aborted, when I compiled with gcc -fstack-protector-all, the glibc abort disappeared as well. So, this hasn't helped me identify the problem yet.
