(ITS#8440) syncrepl improvements for delta-sync mmr
by quanah＠openldap.org 09 Jun '16

09 Jun '16

Full_Name: Quanah Gibson-Mount Version: 2.4.44 OS: Linux 2.6 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (75.111.52.177) Syncprov currently skips contextCSN updates to the main DB, but not the accesslog DB in delta-syncrepl configurations. Consumers correctly ignore this traffic with "CSN too old" messages, but the syncprov code to ignore the updates in the main db should be extended to cover the accesslog DB to cut out this unnecessary traffic.

Re: (ITS#8433) slapd deadlocks on shutdown in 3+ MMR configuration with active writes

There's not much we can do in > slapd about this. Going back through my notes on when we hit this before with customers, the following are the steps necessary to trigger these deadlocks: a) Must have 2+ replication agreements per node. This will not occur in 2 MMR node environments b) starttls is used in all the replication agreements c) There needs to be fairly consistent write traffic After some point of time, slapd will then deadlock on shutdown. Or, if allowed to run long enough, it will grind completely to a halt (2-3 weeks, depending on traffic). This started after we upgraded to openssl 1.0.1j. It is continuing to occur with openssl 1.0.2h (just to ntoe). --Quanah -- Quanah Gibson-Mount Release and QA Engineer <http://www.openldap.org>

Full_Name: Sudhakar Pittala Version: openldap 2.8 OS: SUSE11.4 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (192.176.1.87) Hi, We are using a OPEN SUSE 11.4 LINUX OS machine. Initially ldap process was running fine. Recently we have restarted this machine and after restart we have found that ldap service was not running. So I have tried to start/restart ldap server using Yast and command line but couldn't succeed. Output from Yast: /etc/init.d/ldap start returned 1 (unspecified error): Output from command line: SLS001:/etc/init.d # ./ldap restart redirecting to systemctl redirecting to systemctl Shutting down ldap-server done redirecting to systemctl Starting ldap-server failed File /var/log/localmessages shows below entries.

No, that's not its purpose. If anything fails, the entire config entry must be wiped out.

Would you please try a more recent version? openldap 2.4.40 is available in jessie and in wheezy-backports. If you can reproduce the problem with this version, please report the bug to the Debian bug tracker. openldap 2.4.44 sources are available from openldap.org, and binary packages are available from ltb-project.org. If you can reproduce the problem with this version, please follow up to this ITS.
