Hi, Thierry,
Where can I see the relation between 389 DS 7.9.* versions and 1.3.*
versions of 389-ds-base to keep track of the expected changes?
This is comparing upstream verses downstream. It's not so straightforward:
Downstream (search for 389-ds-base) on
https://brewweb.engineering.redhat.com/brew/
For example;
https://brewweb.engineering.redhat.com/brew/buildinfo?buildID=2386883
Upstream you can do git log on the 1.3.x tags:
$ git clone https://github.com/389ds/389-ds-base.git ; cd 389-ds-base
$ git checkout 389-ds-base-1.3.11.1
$ git log --oneline
HTH,
Mark
Thank you,
- Alex

*Subject: *[389-users] Re: 389 DS memory growth
Hi,
Thanks for raising this issue. Actually the version is an upgrade of
389 7.9.18 to 7.9.21. It contains only 3 bug fixes
- 5497: boolean attribute should be case insensitive
- 5440: memberof can be slow when multiple membership attribute are
defined
- 5565: support of PBKDF2-SHA512 in 7.9
The usual option would be to use valgrind to debug the leak. Because
of the limited list of bug we can also try to eliminate candidate. I
think the first one looks safe. For 5440, do you use memberof and with
how many membership attributes. For 5565, what is your default
password storage scheme ? if it is PBKDF2-SHA512, could you set it to
PBKDF2-SHA256 and monitor memory consumption ?

We’ve been experiencing similar memory growth. I’ve had to
quadruple RAM on our ldap hosts, but things seem stable there.
Still unsure what the cause is. Glad to hear at least that someone
else is seeing the same issue, so I can perhaps rule out an
environmental change.

Hello colleagues,
On March 22nd we updated the 389-ds-base.x86_64 and
389-ds-base-libs.x86_64 packages on our eight RHEL 7.9
production servers from version 1.3.10.2-17.el7_9 to version
1.3.11.1-1.el7_9. We also updated the kernel from kernel
3.10.0-1160.80.1.el7.x86_64 to
kernel-3.10.0-1160.88.1.el7.x86_64 during the same update.
Approximately 12 days later, on April 3rd, all the hosts
started exhibiting memory growth issues whereby the “slapd”
process was using over 90% of the available system memory of
32GB, which was NOT happening for a couple of years prior to
applying any of the available package updates on the systems.
Two of the eight hosts act as Primaries (formerly referred to
as masters), while 6 of the hosts act as read-only replicas.
Three of the read-only replicas are used by our authorization
system while the other three read-only replicas are used by
customer-based applications.
Currently we use system controls to restrict the memory usage.
My question is whether this is something that other users also
experience, and what is the recommended way to stabilize the
DS servers in this type of situation?
Thanks,
- Alex
