(ITS#5250) CVSWeb log file issue
by quanah＠OpenLDAP.org 28 Nov '07

28 Nov '07

Full_Name: Quanah Gibson-Mount Version: NA OS: NA URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (38.104.138.6) The log for the file is not complete when viewed via cvsweb. This is easily apparent when looking at the changes for doc/man/man5/slapd.conf.5, as it is missing recent commits. --Quanah

Your 2.3.27 is quite old, the current 2.3 is 2.3.39. There are no known leaks related to the loglevel though. That sounds more like a memory leak in your platform's C library, in the syslog() function. You would need to use a malloc debugger to verify that. > My openLDAP DB is divided into 3 physical DBs, each of 4 GB , 12 GB and 26 GB > sizes , 42 GB total. > > We were running with ldbm backend till 6-7 months back when the total size of > the DB was below 30 GB.

(ITS#5249) OpenLDAP memory leak
by sumith.narayanan＠gmail.com 28 Nov '07

28 Nov '07

Full_Name: Sumith Narayanan Version: 2.3.27 OS: MacOSX 10.4 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (17.216.21.198) My openLDAP DB is divided into 3 physical DBs, each of 4 GB , 12 GB and 26 GB sizes , 42 GB total. We were running with ldbm backend till 6-7 months back when the total size of the DB was below 30 GB. It started crashing once in a while as the size started increasing. We then changed the backend to Berkeley DB (Version:4.4.20) and the openLDAP version 2.3.27. It is running in a 8 GB memory machine with 32 bit processing and receives updates through an custom interface which binds to ldap and do the update / inserts and deletes. The rate at which the updates/inserts/deletes come is around 1-2 K / hr. Now when I start the slapd process in loglevel 256 or 512 , it starts crashing with in a few hours running out of memory. The maximum memory that 32 bit processor can use is around 2 GB. It crashes after that. I was trying to tune the DB_CONFIG : DB_CONFIG settings for each DB : For 26 GB DB. set_cachesize 0 42428800 0 # Transaction Log settings set_lg_regionmax 1048576 set_lg_max 20485760 set_lg_bsize 2097152 For 12GB DB set_cachesize 0 15485760 0 set_lg_regionmax 1048576 set_lg_max 20485760 set_lg_bsize 2097152 for 4 GB DB set_cachesize 0 10485760 0 set_lg_regionmax 1048576 set_lg_max 10485760 set_lg_bsize 2097152 Slapd.conf settings : loglevel 16 gentlehup on idletimeout 300 sizelimit 1000 timelimit 300 password-hash {SSHA} allow bind_v2 threads 32 These parameters are set same for all the three DBs : dbcachesize 100000 cachesize 100000 There is a replica also which gets updates from the master. Now when I change the loglevel to 32 or 16 , the process lives longer , sometimes for a week or for more than a month.... However , as soon as I switch back to old loglevel , it starts crashing. This is happening in both master and slave. Could you please advice whether there is a fix for this in the current version or is it getting fixed in the coming version OR is it something that I can fix by configuring. Logs are important for us as we need to know where the requests are coming from. Also , the DB is accessed 250 K times in a day approximately. Please let me know if I need to furnish any more details. Thanks, Sumith.

(ITS#5248) non-atomic signal variables
by h.b.furuseth＠usit.uio.no 27 Nov '07

27 Nov '07

Full_Name: Hallvard B Furuseth Version: HEAD OS: URL: Submission from: (NULL) (129.240.6.233) Submitted by: hallvard Some non-atomic variables are used both outside and inside signal handlers: clients/tools/common.c: static int gotintr; static int abcan; servers/slapd/daemon.c: static volatile int waking; (used via WAKE_LISTENER in signal handler) slapd/slapcat.c: static int gotsig; They need to be volatile sig_atomic_t. That can be signed or unsigned char, so abcan must be set to some #define in range 0..127 instead of -1. Two more problems: WAKE_LISTENER will not be correct anyway since it does '++waking' (not atomic) and is called both inside and outside a signal handler. The !NO_THREADS version is OK. For that matter, behavior is only defined when the signal handler _writes_ a volatile sig_atomic_t, not when it _reads_ it: http://groups.google.no/group/comp.std.c/msg/d01196111ce93615 Dunno what the problem is, or if it is worse than variables accessed by threads. I don't see anything to do about it either.

(ITS#5247) ldapmodify results misleading
by quanah＠OpenLDAP.org 27 Nov '07

27 Nov '07

Full_Name: Quanah Gibson-Mount Version: HEAD OS: NA URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (76.21.80.71) When ldapmodify prints "modify complete" all it has done so far is send the request to the server. It hasn't actually read the server's reply yet. This should be fixed so that better information is given to the end client about the state of the modify request.

For other log levels things seem to work. The problem > has been seen on x86_64 (segfaults are logged in syslog). If you want to report bugs in OpenLDAP through the OpenLDAP ITS you should always test if the bug is present in most recently release version of the software (2.3.39 in this case). If you want to report bugs against older Versions, that were shipped with a product of some vendor you should report the bug to the vendor of that product. So in your case please either test with OpenLDAP 2.3.39 (you can find SLES packages here: http://download.opensuse.org/repositories/OpenLDAP/SLE_10/ Or report the bug to SUSE/Novell here: http://support.novell.com/additional/bugreport.html or, if you have a valid support contract to you contact in support. Btw, I have some x86_64 SLES10-SP1 systems with openldap-2.3.32 running here with 'loglevel 0' without any problem, so I suspect there are some additional things that trigger your problem. But to go further please choose one of the options I gave you above -- Ralf -------------------------------------------------------------------------- SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nürnberg)
