RE24 (2.4.15) slapd consuming large amounts of CPU
by John Morrissey 30 Mar '09

30 Mar '09

I upgraded one of our consumers to 2.4.15 recently, from RE24 as of 20090113. Its configuration stayed the same, save for bumping the BDB cache size from 256MB to 2GB. After a few hours of uptime, slapd suddenly begins consuming enormous amounts of CPU (a three- to four-fold increase over less than a few minutes, and is sustained until slapd is restarted). A backtrace (below) shows many threads waiting on a mutex in bdb_cache_*(). This is with BDB 4.7 (with all patches applied) on Debian lenny. 'db_stat -c' output is below (and looks sane), in case that's useful. Thinking thread contention, I bumped the worker thread count (slapd.conf threads directive) down from 32 to 8, which has made no difference. john DB_CONFIG: set_lg_max 10485760 set_lg_bsize 2097152 set_cachesize 2 0 0 290 Last allocated locker ID 0x7fffffff Current maximum unused locker ID 9 Number of lock modes 1000 Maximum number of locks possible 1000 Maximum number of lockers possible 1000 Maximum number of lock objects possible 20 Number of lock object partitions 39 Number of current locks 574 Maximum number of locks at any one time 16 Maximum number of locks in any one bucket 0 Maximum number of locks stolen by for an empty partition 0 Maximum number of locks stolen for any one partition 275 Number of current lockers 277 Maximum number of lockers at any one time 39 Number of current lock objects 321 Maximum number of lock objects at any one time 5 Maximum number of lock objects in any one bucket 0 Maximum number of objects stolen by for an empty partition 0 Maximum number of objects stolen for any one partition 3854M Total number of locks requested (3854398087) 3854M Total number of locks released (3854395960) 0 Total number of locks upgraded 29 Total number of locks downgraded 11921 Lock requests not available due to conflicts, for which we waited 2088 Lock requests not available due to conflicts, for which we did not wait 0 Number of deadlocks 0 Lock timeout value 0 Number of locks that have timed out 0 Transaction timeout value 0 Number of transactions that have timed out 736KB The size of the lock region 827752 The number of partition locks that required waiting (0%) 117449 The maximum number of times any partition lock was waited for (0%) 0 The number of object queue operations that required waiting (0%) 535994 The number of locker allocations that required waiting (0%) 268 The number of region locks that required waiting (0%) 5 Maximum hash bucket length [Switching to Thread 0x7f1ac33876e0 (LWP 2258)] 0x00007f1ac14d0715 in pthread_join () from /lib/libpthread.so.0 Thread 14 (Thread 0x46e2c950 (LWP 2483)): #0 0x00007f1ac14d3d29 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/libpthread.so.0 No symbol table info available. #1 0x00007f1ac2f4019d in ldap_int_thread_pool_wrapper (xpool=<value optimized out>) at /tmp/buildd/openldap-2.4.15/libraries/libldap_r/tpool.c:654 pool = (struct ldap_int_thread_pool_s *) 0x16a1810 task = (ldap_int_thread_task_t *) 0x0 work_list = (ldap_int_tpool_plist_t *) 0x1382501 ctx = {ltu_id = 1189267792, ltu_key = {{ltk_key = 0x431480, ltk_data = 0x22e9bf0, ltk_free = 0x431550 <conn_counter_destroy>}, {ltk_key = 0x485650, ltk_data = 0x22e9d00, ltk_free = 0x485150 <slap_sl_mem_destroy>}, {ltk_key = 0x17b05b0, ltk_data = 0x23e9d50, ltk_free = 0x7f1abe04f900 <bdb_reader_free>}, {ltk_key = 0x445410, ltk_data = 0x7f19f010d170, ltk_free = 0x4451e0 <slap_op_q_destroy>}, {ltk_key = 0x7f1abe0425a0, ltk_data = 0x7f1a0fffc010, ltk_free = 0x7f1abe042660 <search_stack_free>}, {ltk_key = 0x17acca0, ltk_data = 0x7f1a14549930, ltk_free = 0x7f1abe04f900 <bdb_reader_free>}, {ltk_key = 0x0, ltk_data = 0x7f19d16b7a40, ltk_free = 0}, {ltk_key = 0x0, ltk_data = 0x0, ltk_free = 0} <repeats 25 times>}} kctx = <value optimized out> keyslot = 641 hash = <value optimized out> __PRETTY_FUNCTION__ = "ldap_int_thread_pool_wrapper" #2 0x00007f1ac14cffc7 in start_thread () from /lib/libpthread.so.0 No symbol table info available. #3 0x00007f1ac12455ad in clone () from /lib/libc.so.6 No symbol table info available. #4 0x0000000000000000 in ??

Re: slapd syncrepl consumer having permanent high CPU load

Howard, I'm not sure if my e-mail was received by the list and then I'm sending it again. Looks like there is an issue with consumer in a provider/consumer configuration in HEAD 2.4.15 version. The consumer doesn't get sync and stay with a high CPU and memory consumption. Please check files attached with full information. Regards, Rodrigo.

search-filter processing within overlay? (struct Filter)
by Daniel 29 Mar '09

29 Mar '09

Hi Folks, I'm currently making my first steps into overlay development using OpenLDAP 2.4.15. Digging into some already existing overlays was very helpful. Thanks to the nice work! My sample overlay is just for personal testing to get some kind of feeling how to handle the slapd(-overlay) API. All I want to do with my testing-overlay is to get some kind of datastructure-list of the attribute names used in the current search-filter. For example processing the following filter (&(objectClass=*)(ou=test)(hasSubordinates=TRUE)) my overlay's _search-callback() should print out "objectClass, ou, hasSubordinates". Of course I could (regexp) string-compare the filterstr contained in struct Filter but I thought there has to be a more slapd-API'ic way available. After browsing through the mailinglist and various openldap-source files my perhabs silly question is: Is there some kind of Attribute-list (Attribute *) datastructure available that can be traversed (in a more linear way) getting the attributes (and might be the corresponding search-patterns used in a search-filter statement? By linaer I mean some kind of (pseudo-code): Attribute attr; for(attr=filter->attrs;attr;attr=attrs->next;) { attr->a_desc... ... } All I've seen so far is struct Filter with it's "filterstr" (char *) and its various pointers to f_desc, f_av_desc, f_and, f_or, f_list and so on. I've also had a look into function "test_filter()" and into translucent-overlay search-callback, both use switch-case constructions to strip (complex) filter-strings (struct Filter) into atoms. I think that's nearly what I would need - again. ;-) Because the filter atomization has already been done during filter-processing my actual intention is to avoid coding (90% copy&paste) the nearly same filter-processing mechanism into my own overlay's _search()-callback in favor to use a might be already existing datastructure. In the moment I'm in doubt splitting the search filter twice could not be very elegant nor very efficient regarding the resulting performance... Probably I've not understood the overlay-processing and datastructures correct, thus I'm looking forward to your advice, hints and help. Thanks a lot! Cheers Daniel

dynlist and memberOf Overlay Combo
by Pete Giesin 26 Mar '09

26 Mar '09

I am attempting to combine the dynlist overlay with the memberOf overlay. I have the following configuration: overlay dynlist dynlist-attrset groupOfURLs memberURL member overlay memberof memberof-group-oc groupOfURLs memberof-member-ad member memberof-memberof-ad memberOf I then have inserted the following entries: dn: uid=test1,ou=People,dc=hcm,dc=com objectClass: top objectClass: person objectClass: inetOrgPerson uid: test1 cn: test1 sn: account dn: cn=WebSelfServiceUser,ou=group,dc=hcm,dc=com cn: WebSelfServiceUser objectClass: groupOfURLs memberURL: ldap:///ou=people,dc=hcm,dc=com??one?(objectClass=inetOrgPerson) If I query the WebSelfService group it indicates that test1 is a member of the group. However, the memberOf attribute never gets set on the user entry. I think the issue is that the dynamic group never gets updated and hence doesn't force the memberOf updates. Is it possible to combine these two overlays? Thanks, Pete

Problem with searches
by Angel L. Mateo 26 Mar '09

26 Mar '09

Hello, I have a problem with my ldap servers. We have a farm of 4 openldap servers that synchronizes its information from a fifth. These servers are used as user backend for our mail system. The problem we have is that sometimes mail systems launchs searches and get 0 entries, but there are entries matching the query. In fact, if they launch the query after a few seconds, it gets the results. My ldap servers are debian servers (etch version) with openldap 2.3.30-5 (debian version) and 1GB of memmory running in a xen VM. These are the logs I get (these are from a script that joins the logs of the ldap server by operation). The two first gets 0 entries, but the third (launched from the same client and the same ldap user) gets 1 entry. Between the queries there were no modification operation (add, mod or del) with this entry: Mar 24 11:01:59 canis2 conn=202855 op=43 (IP=155.54.212.199) SRCH (base=ou=Usuarios,dc=Telematica, scope=2, filter=(&(objectClass=posixAccount)(uid=lsc63903)(irisUserStatus=urn:mace:rediris.es:um.es:userstatus:correo:estado:activo)), attr=uid userPassword uidNumber gidNumber cn homeDirectory loginShell gecos description objectClass ) -> tag=101, err=0, text= , nentries=0 Mar 24 11:01:59 canis2 conn=202855 op=44 (IP=155.54.212.199) SRCH (base=ou=Usuarios,dc=Telematica, scope=2, filter=(&(objectClass=posixAccount)(uid=lsc63903)(irisUserStatus=urn:mace:rediris.es:um.es:userstatus:correo:estado:activo)), attr=uid userPassword uidNumber gidNumber cn homeDirectory loginShell gecos description objectClass ) -> tag=101, err=0, text= , nentries=0 Mar 24 11:32:10 canis2 conn=696 op=101481 (IP=) SRCH (base=ou=Usuarios,dc=Telematica, scope=2, filter=(&(objectClass=posixAccount)(uid=lsc63903)(irisUserStatus=urn:mace:rediris.es:um.es:userstatus:correo:estado:activo)), attr=uid userPassword uidNumber gidNumber cn homeDirectory loginShell gecos description objectClass ) -> tag=101, err=0, text= , nentries=1 Any idea? -- Angel L.

sladp crash during stress test
by Pete Giesin 26 Mar '09

26 Mar '09

I was performing some stress tests and the slapd server crashed. The only log information I can find as to why the server crashed is the following: Mar 25 12:30:53 PAS209 kernel: slapd[29502] general protection rip:3004a71650 rsp:4136db70 error:0 Mar 26 01:09:24 PAS209 kernel: slapd[1514]: segfault at 0000000000000000 rip 00002aab11868901 rsp 0000000042f7ae68 error 6 I know this is not much to go on but I was hoping someone might be able to help explain why the server crashed. I am running Symas OpenLDAP 2.4.12.1 on Red Hat Enterprise Linux 5.2 x86_64. I was running a test with a read-to-write ratio of 999-1. The test was using 10 clients with 30 threads per client. Two distinct users were being modified and all of the users were being searched randomly. Thanks, Pete

Installaing openldap 2.4 in ubuntu 8.04 whith libdb4.6 (or higher)
by fida aljounaidi 26 Mar '09

26 Mar '09

Hi I upgrade my server Os (from feisty to hardy) to install the last ubuntu packaged version of openldap (slapd 2.4.9). I want to use also the db4.6 utils with this version to do a better tuning of DB_CONFIG. The problem is that this version is packaged with libdb4.2 dependency. With this version of Berkley DB, I've observed an important amount of CPU consumed when synchronisation between master and slaves is executed. This led sometimes in loss of synchronisation state. So, I have 2 questions: is it any know bug in libdb4.2 that can lead to this beahaviour ? is it better ton install openldap from package Source so that i can configure it with higher version of libdb ? Thank you P.S: Sorry for my english

Mirrormode and cn=config
by Peter Mogensen 26 Mar '09

26 Mar '09

Hi, I'm doing a mirrormode setup from what I can understand of the admin guide A.2.5 it's possible to mirror cn=config so you only have to make changes on one server. I have two problems though. First: I've looked at test49 and it doesn't seem to use mirrormode. Also - server 1 in test49 has it self as provider ??? I would guess that there would be some troubles with mirroring cn=config since, server 1 should have server 2 as provider and vice-versa. (and that must not be replicated) Is this possible at all or am I chasing a dead end? Second: I have problem with SASL/EXTERNAL and TLS. The server can't seem to find the client certificate. I'm using slapd from Debian Lenny and Ubuntu Hardy, and it's probably due to GnuTLS problems. I get error from slapd like: "TLS: can't accept: A TLS packet with unexpected length was received.." "unable to get TLS client DN, error=-4 id=0" Are GnuTLS just completely broken on Debian Lenny or can this be made to work? /Peter
