Logs show nothing, no activity. Connect via ldapmodify or other cli utilities just hangs. In such a situation rebooting a single node of the cluster helps, until the cluster becomes unresponsive once again. Please tell me what could be the problem? Could my cluster configuration be incorrect? The problem manifests itself only in situation where I have many databases, e.g. more than 10. With one-two dbs all works as expected. I have also tried using different in-built database backends, to no avail. -- 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 23 Apr '21

23 Apr '21

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.

[Issue 9470] New: Add homedir overlay to core

https://bugs.openldap.org/show_bug.cgi?id=9470 Issue ID: 9470 Summary: Add homedir overlay to core Product: OpenLDAP Version: 2.5 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: quanah(a)openldap.org Target Milestone: --- Symas will contribute its homedir overlay as a core overlay Home directory provisioning overlay The homedir overlay causes slapd to notice changes involving RFC-2307bis style user-objects and make appropriate changes to the local filesystem. This can be performed on both master and replica systems, so it is possible to perform remote home directory provisioning. -- You are receiving this mail because: You are on the CC list for the issue.

https://bugs.openldap.org/show_bug.cgi?id=8721 --- Comment #5 from Shawn McKinney <smckinney(a)symas.com> --- It has been observed that the quarantine is reset on each search, even if the server is restarted. Another scenario 1. stop louie 2. perform search, 20 second quarantine starts 3. start louie 4. perform another search before quarantine lifts, it resets to another 20 seconds -- You are receiving this mail because: You are on the CC list for the issue.
