(ITS#6331) slapd freezing, not accepting further 'write' operations while 'read' operations are unaffected
by j＠telepaths.org 13 Oct '09

13 Oct '09

Full_Name: Jeff Doyle Version: 2.4.17 OS: Debian/Lenny URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (130.94.106.251) Greetings, Occasionally, I will find one of my servers (running Debian/Lenny with back-ported slapd version 2.4.17) in a state where the following occurs: * Write operations will 'freeze' - leaving the requester at a frozen prompt or frozen LDAP-client of some kind (from wherever the write-operation originated). * slapd refuses to 'stop', even though it indicates that its waiting for "0" processes to complete. * Logs do not indicate a segfault nor any poorly terminated processes. * Read operations on same server continue to function normally. Any data that existed before the "freeze" is returned as it should be. Modules used: * accesslog * back_hdb * back_monitor * back_relay * back_rwm * syncprov Servers are all fairly new, and reasonably beefy for their purposes: * 6GB RAM * 2+ GHz CPU, all QuadCore Xeon and all running amd64 kernel (current with Lenny) * Plenty of Disk Space (gigs and gigs) * Servers are SLEEPING (0.00 avg load) slapd is making use of 'tool-threads' with a value of '4' - however changing this value has had no effect - Just a side note. Inform me of any further configs and/or information that you need, and I will provide it promptly. Thanks, Jeff

(ITS#6330) slapd memory leak
by whm＠stanford.edu 13 Oct '09

13 Oct '09

Full_Name: Bill MacAllister Version: 2.4.18 OS: Debian 5.0 URL: http://www.stanford.edu/~whm/files/slapd/readme.html Submission from: (NULL) (75.26.167.150) We have observed what we believe to be a memory leak in OpenLDAP 2.4.18 in testing while dynlist support. We have a script that randomly expands the member lists of groups defined using dynlist. Running this script for a period of about 24 hours forces the slapd process to swap. It is not clear at all that dynlist is the problem because we were not able to see the problem with our test script until we surrounded each query with a bind/unbind. (At least we didn't wait long enough to see it.) All queries perform GSSAPI binds to the directory. The problem is unaffected by using either the MIT or Heimdal GSSAPI libraries. Our build of OpenLDAP 2.4.18 follows the debian configuration with the exceptions: * Patch for ITS6287 * Patch for ITS6308 * Patch to the index slots * disable support for tcp_wrappers and disable rlookups The details of software versions, build options, slapd configuration, scripts, db_stat output and testing procedures are at http://www.stanford.edu/~whm/files/slapd/readme.html.

(ITS#6329) memberof overlay doesn't update entryCSN
by msmith＠cbnco.com 13 Oct '09

13 Oct '09

Full_Name: Michael Smith Version: 2.4.18-55.1 OS: SLES11 (SUSE) URL: Submission from: (NULL) (207.164.182.8) Hi, It looks like the memberof overlay doesn't update a user object's entryCSN when a group object is changed. I believe this causes trouble with syncrepl, at least in a multi-master configuration: if one node is down when the group object is changed, it won't know it needs to update the user object when it comes back. I'm a little confused because while the entryCSNs don't change on the server where the group is updated, they do change on the other servers in the replication group. For example, if I add a user to a group on node 2, the user's entryCSN on node 2 might be "20091008032402.932100Z#000000#002#000000": old timestamp, correct server ID. On node 1 the entryCSN might be "20091008032142.915412Z#000000#002#000000": current timestamp, correct server ID. I'm using syncrepl with refreshAndPersist and syncprov. The memberof overlay is using its default configuration. In the stacking order, memberof comes before syncprov, but it behaved the same way in both orders. All nodes are configured with memberof and syncprov. The servers' clocks are in sync (NTP). There was a thread on openldap-software here: http://thread.gmane.org/gmane.network.openldap.general/45790/focus=45808 This is what my configuration looks like on node 1: dn: cn=config # ... olcServerID: 1 dn: olcDatabase={1}hdb,cn=config # ... olcAccess: {0}to attrs=userPassword by self write by dn.subtree="ou=service,dc=dom" read by * auth olcAccess: {1}to attrs=shadowLastChange by self write by * read olcAccess: {2}to attrs=userPKCS12 by self read by * none olcAccess: {3}to * by * read olcDbIndex: objectclass eq olcDbIndex: entryUUID eq olcDbIndex: entryCSN eq olcLimits: {0}dn.subtree="ou=service,dc=dom" time.soft=unlimited time.hard=unlimited size.soft=unlimited size.hard=unlimited olcSyncrepl: {0}rid=002 provider=ldap://ldap2.dom binddn="cn=repluser,ou=service,dc=dom" bindmethod=simple credentials=xxxxxx searchbase="dc=dom" attrs="*,+" type=refreshAndPersist schemachecking=off tls_cacert=/etc/openldap/ssl/ca.crt tls_reqcert=demand interval=00:00:05:00 retry="60 +" olcMirrorMode: TRUE dn: olcOverlay={0}memberof,olcDatabase={1}hdb,cn=config objectClass: olcOverlayConfig olcOverlay: {1}memberof dn: olcOverlay={1}syncprov,olcDatabase={1}hdb,cn=config objectClass: olcSyncProvConfig olcSpCheckpoint: 100 10 olcSpSessionlog: 1000 olcOverlay: {0}syncprov Node 2 looks the same, but with olcServerID: 2 and provider=ldap://ldap1.dom. Thanks, Mike

Full_Name: HervE Version: 2.2.29 OS: Windows XP URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (213.41.232.181) I am trying to configure BusinessObjects in order to use OpenLDAP with it. In the LDAP authentification menu in BO, I have to map all the following attributes with the appropriate tags: Mappings of LDAP server attributes Object class: Static Group: Member of static group: Dynamic Group: Dynamic Group Filter: Group description: User object Class: Username: Full name of the user: Email User: User Description: Default LDAP search attributes Default group research attribute: Default user research attribute: Can anyone help me please?

OpenLDAP ITS: OK the issue is looking more and more like buggy slapd behavior. I have now narrowed down the issue to an instance where slapd is partially "hung" and will not stop nor restart. This directly correlates to replication breaking because SLAPD is breaking: Oct 11 18:22:08 server1 slapd[10771]: <= bdb_equality_candidates: (uidNumber) not indexed Oct 11 18:22:08 server1 slapd[10771]: <= bdb_equality_candidates: (gidNumber) not indexed Oct 11 18:22:08 server1 slapd[10771]: <= bdb_equality_candidates: (uidNumber) not indexed Oct 11 18:46:41 server1 slapd[10771]: <= bdb_equality_candidates: (uidNumber) not indexed Oct 11 18:48:37 server1 slapd[10771]: <= bdb_equality_candidates: (uidNumber) not indexed Oct 11 18:49:05 server1 slapd[10771]: daemon: shutdown requested and initiated. Oct 11 18:49:05 server1 slapd[10771]: slapd shutdown: waiting for 0 operations/tasks to finish As you can see, the exact time when this occurs doesn't bring anything interesting to the logs. You can see the repeated string of index warnings (not an issue, just haven't indexed this attribute yet) followed by my attempt to restart slapd when I receive a notification indicating there is a replication discrepancy. I have grepped through all of my logs (dmesg, debug, syslog) for anything related to slapd. What you see above is the more interesting of the hits returned. PLEASE help -- the issue is getting more serious now, and by the evidence I've presented, is looking more and more out of my control. You've seen my config - can anyone think of why this would happen? It seems vaguely like a locking issue .... Thanks Jeff
