[Issue 10413] New: Consumer prepares cookie too early
by openldap-its＠openldap.org 09 Mar '26

09 Mar '26

https://bugs.openldap.org/show_bug.cgi?id=10413 Issue ID: 10413 Summary: Consumer prepares cookie too early Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- A consumer prepares its cookie at the moment its task is started (in do_syncrep1), then calls ldap_sync_search, but this is where we can figure out if there's another refresh running already and suspend the task. When that other refresh finishes and tells another one to resume, we just call ldap_sync_search so keep the old cookie rather than update it to match what we now know. This doesn't affect correctness but forces the other provider(s) to reiterate something the consumer already knows, this can be very expensive for both. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10368] New: Must revert ITS#9849 license changes

https://bugs.openldap.org/show_bug.cgi?id=10368 Issue ID: 10368 Summary: Must revert ITS#9849 license changes Product: website Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: major Priority: --- Component: website Assignee: bugs(a)openldap.org Reporter: hyc(a)openldap.org Target Milestone: --- The changes related to license.wml made for ITS#9849 must be reverted. There is only one OpenLDAP Public License and it applies to all OpenLDAP software. There are not two different licenses for release/LTS. No single person has the right to alter the existing license. Currently the website is broken, as https://openldap.org/software/release/license.html is an empty file. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10404] New: slapd uses all available memory and starts using swap
by openldap-its＠openldap.org 23 Feb '26

https://bugs.openldap.org/show_bug.cgi?id=10404 Issue ID: 10404 Summary: slapd uses all available memory and starts using swap Product: OpenLDAP Version: 2.6.10 Hardware: x86_64 OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: tomas.bjorklund(a)su.se Target Milestone: --- We have a problem with slapd using more and more memory until in starts using swap. We are using mdb and our maxsize is set to 8192000000. The server has 32GB of ram. data.mdb is around 2.6 GB Some settings from our slapd.conf: sizelimit 5000 timelimit 600 checkpoint 1024 15 loglevel sync stats This is how it looks with top: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 314486 root 20 0 31.6g 26.2g 2.6g S 16.3 83.7 8,09 slapd Depending on the load of the server it usually takes 2 weeks until all memory has been used. Things that we have tried: Changed swapiness to 1 Changed slapd service to use this: [Service] Environment="LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libtcmalloc_minimal.so.4" LimitCORE=infinity LimitNOFILE=4096 Restart=on-failure TimeoutStopSec=900 Everything worked fine with bdb and cache settings like: cachesize 100000 idlcachesize 100000 But since switching to mdb we run out of memory. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9513] New: Enhanced debug output
by openldap-its＠openldap.org 12 Feb '26

12 Feb '26

https://bugs.openldap.org/show_bug.cgi?id=9513 Issue ID: 9513 Summary: Enhanced debug output Product: OpenLDAP Version: 2.5 Hardware: All OS: All Status: UNCONFIRMED Severity: enhancement Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: hyc(a)openldap.org Target Milestone: --- While debugging ITS#9479 I needed more information on which threads were doing what actions. Also, when looking for delays/hangs/race conditions, the 1-second granularity of the debug msg timestamp was inadequate. And also, some of the debug output for the Search operation was being done in separate Debug calls for a single line of output. This gets jumbled up pretty badly if other threads are printing output as well. New patch set will extend the debug timestamp to have fractional seconds too; it will use clock_gettime for nanosecond resolution if available, otherwise use gettimeofday for microsecond resolution. Also tweak the Search debug output to only use one Debug invocation per line of output. This is MR!279. -- You are receiving this mail because: You are on the CC list for the issue.
