It appears to affect other platforms as well: https://bugzilla.redhat.com/show_bug.cgi?id=967719 Most likey you will need to build your own libperl in order to fix this, tho at the moment I have no idea what perl configuration changes will be required. 5259e408 conn=1000 op=1 do_add ber_scanf fmt ({m) ber: 5259e408 conn=1000 op=1 do_add: dn (olcDatabase=perl,cn=config) ber_scanf fmt ({m{W}}) ber: ber_scanf fmt ({m{W}}) ber: ber_scanf fmt ({m{W}}) ber: ber_scanf fmt ({m{W}}) ber: ber_scanf fmt ({m{W}}) ber: ber_scanf fmt ({m{W}}) ber: ber_scanf fmt ({m{W}}) ber: ber_scanf fmt ({m{W}}) ber: ber_scanf fmt ({m{W}}) ber: ber_scanf fmt ({m{W}}) ber: ber_scanf fmt ({m{W}}) ber: ber_scanf fmt ({m{W}}) ber: ber_scanf fmt ({m{W}}) ber: ber_scanf fmt ({m{W}}) ber: ber_scanf fmt (}) ber: 5259e408 >>> dnPrettyNormal: <olcDatabase=perl,cn=config> => ldap_bv2dn(olcDatabase=perl,cn=config,0) <= ldap_bv2dn(olcDatabase=perl,cn=config)=0 => ldap_dn2bv(272) <= ldap_dn2bv(olcDatabase=perl,cn=config)=0 => ldap_dn2bv(272) <= ldap_dn2bv(olcDatabase=perl,cn=config)=0 5259e408 <<< dnPrettyNormal: <olcDatabase=perl,cn=config>, <olcDatabase=perl,cn=config> 5259e408 >>> dnPretty: <dc=mydomain,dc=org> => ldap_bv2dn(dc=mydomain,dc=org,0) <= ldap_bv2dn(dc=mydomain,dc=org)=0 => ldap_dn2bv(272) <= ldap_dn2bv(dc=mydomain,dc=org)=0 5259e408 <<< dnPretty: <dc=mydomain,dc=org> 5259e408 >>> dnNormalize: <dc=mydomain,dc=org> => ldap_bv2dn(dc=mydomain,dc=org,0) <= ldap_bv2dn(dc=mydomain,dc=org)=0 => ldap_dn2bv(272) <= ldap_dn2bv(dc=mydomain,dc=org)=0 5259e408 <<< dnNormalize: <dc=mydomain,dc=org> 5259e408 >>> dnPretty: <cn=Manager,dc=mydomain,dc=org> => ldap_bv2dn(cn=Manager,dc=mydomain,dc=org,0) <= ldap_bv2dn(cn=Manager,dc=mydomain,dc=org)=0 => ldap_dn2bv(272) <= ldap_dn2bv(cn=Manager,dc=mydomain,dc=org)=0 5259e408 <<< dnPretty: <cn=Manager,dc=mydomain,dc=org> 5259e408 >>> dnNormalize: <cn=Manager,dc=mydomain,dc=org> => ldap_bv2dn(cn=Manager,dc=mydomain,dc=org,0) <= ldap_bv2dn(cn=Manager,dc=mydomain,dc=org)=0 => ldap_dn2bv(272) <= ldap_dn2bv(cn=manager,dc=mydomain,dc=org)=0 5259e408 <<< dnNormalize: <cn=manager,dc=mydomain,dc=org> 5259e408 oc_check_required entry (olcDatabase=perl,cn=config), objectClass "olcDbPerlConfig" 5259e408 oc_check_allowed type "objectClass" 5259e408 oc_check_allowed type "olcDatabase" 5259e408 oc_check_allowed type "olcSuffix" 5259e408 oc_check_allowed type "olcAddContentAcl" 5259e408 oc_check_allowed type "olcLastMod" 5259e408 oc_check_allowed type "olcMaxDerefDepth" 5259e408 oc_check_allowed type "olcReadOnly" 5259e408 oc_check_allowed type "olcRootDN" 5259e408 oc_check_allowed type "olcRootPW" 5259e408 oc_check_allowed type "olcSyncUseSubentry" 5259e408 oc_check_allowed type "olcMonitoring" 5259e408 oc_check_allowed type "olcPerlModulePath" 5259e408 oc_check_allowed type "olcPerlModule" 5259e408 oc_check_allowed type "olcPerlFilterSearchResults" 5259e408 oc_check_allowed type "structuralObjectClass" 5259e408 >>> dnNormalize: <olcDatabase={3}perl> 5259e408 <<< dnNormalize: <olcDatabase={3}perl> 5259e408 >>> dnPrettyNormal: <dc=mydomain,dc=org> => ldap_bv2dn(dc=mydomain,dc=org,0) <= ldap_bv2dn(dc=mydomain,dc=org)=0 => ldap_dn2bv(272) <= ldap_dn2bv(dc=mydomain,dc=org)=0 => ldap_dn2bv(272) <= ldap_dn2bv(dc=mydomain,dc=org)=0 5259e408 <<< dnPrettyNormal: <dc=mydomain,dc=org>, <dc=mydomain,dc=org> 5259e408 >>> dnPrettyNormal: <cn=Manager,dc=mydomain,dc=org> => ldap_bv2dn(cn=Manager,dc=mydomain,dc=org,0) <= ldap_bv2dn(cn=Manager,dc=mydomain,dc=org)=0 => ldap_dn2bv(272) <= ldap_dn2bv(cn=Manager,dc=mydomain,dc=org)=0 => ldap_dn2bv(272) <= ldap_dn2bv(cn=manager,dc=mydomain,dc=org)=0 5259e408 <<< dnPrettyNormal: <cn=Manager,dc=mydomain,dc=org>, <cn=manager,dc=mydomain,dc=org> 5259e408 perl backend db init Program received signal SIGSEGV, Segmentation fault.

(ITS#7725) LMDB readahead should be configurable
by hyc＠OpenLDAP.org 13 Oct '13

13 Oct '13

Full_Name: Howard Chu Version: 2.4.35+ OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (78.155.233.73) Submitted by: hyc In 2.4.35 (commit b1da555c4c7275d7f756d693c42814388a9aa839) code was added to unconditionally turn off readahead, because it is harmful to random read performance when a DB is larger than RAM and/or system RAM is already full. Unfortunately turning it off harms sequential read performance. It should be configurable, since different behaviors are needed in different use cases.

Your trace is strange because it shows overlays being used, but test005 doesn't use any overlays.

On a large DB, the previous code used 3276587 pages in slapadd -q, and the new code uses 3272633 pages. It's only a 0.13% savings in this case, it seems the frequency of these insert patterns is quite rare. The runtime is also 1.1% faster going from real 41m35.8s user 50m57.6s sys 5m11.4s to real 41m1.7s user 50m25.8s sys 4m55.3s -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
