You'd have to go back to 389-ds-base-1.3.7, but I don't know if that's possible on CentOS 7.6, you'd probably have to go back to CentOS 7.5 as well I would think. :-(Mark,Thank you for figuring out the issue we are having. Question, is it possible for us to roll back/downgrade the 389-ds to a "previously" working version?

Might have to wait for CentOS to pick up the latest builds?Hi Paul, Okay I think I found the bug you are running into: https://bugzilla.redhat.com/show_bug.cgi?id=1627512 https://pagure.io/389-ds-base/issue/49618 So sounds like you need to upgrade to: 389-ds-base-1.3.8.4-21 (RHEL/Centos 7.6)Or build the upstream 1.3.7 server yourself using the commit found in the pagure ticket above.Looks like 1.3.8.4-22 is going to be in RHEL(Centos) batch update 3. So it's not available yet, sorry, but should be next month (not sure how fast Centos picks up RHEL updates)So in the meantime I would increase the autosize values to take advantage of your RAM. See the wiki link I sent you earlier, and also checkout the admin guide:https://access.redhat.com/documentation/en-us/red_hat_directory_server/10/html/configuration_command_and_file_reference/database_plug_in_attributes#nsslapd_cache_autosize Good luck, MarkRegards, Mark On 1/16/19 11:38 AM, Mark Reynolds wrote:Hey Paul, On 1/16/19 10:14 AM, Paul Whitney wrote:We were on version: 389-ds-base-1.3.7.5-24.What OS?Well setting autosize to zero and explicitly setting the cache attributes is all it should take for it to stickThe nsslapd-cache-autosize was set to 0. We apply our own values.To keep us afloat we have been forced to enable nsslapd-cache-autosize. However, our performance has degraded in response times and feel we are not able to better allocate/customize the cache settings as they relate to each database.System: Virtual Machine 8-CPU 64GB RAM (of which 35G is free) Two databases in the slapd instance: userRoot = 21G groupRoot = 1.8GWhen we try to allocate anything above 50% for nsslapd-cache-autosize, the service fails to start stating values cannot exceed 100.When we disable nsslapd-cache-autosize, and punch in our numbers: nsslapd-cache-autosize = 0 nsslapd-dbcachesize = 1073741824nsslapd-cachememsize = 2147483648 (groupRoot) and 23622320128 (userRoot)Service overwrites our settings and sets both databases to 2147483648. While that is ok for groupRoot, it is not for userRoot.Based on this information, is there a way/recommendation to: 1. To force these values we enter to "stick"Start here: http://www.port389.org/docs/389ds/design/autotuning.html (checkout the manual tuning section)1. How can I better configure the auto cache sizing of these entries?You can tune the autosizing to use more cache, but it is uniform across all backends: groupRoot and userRoot would use the same values.The logs would say why the server thinks it needs to resize your caches (a bug?), but it sounds like autosizing is not the issue here since it is set to zero. I'm not sure what else I can offer up without more log information. I suspect the server is not properly detecting the 64gigs of memory, and thinks you have much less, which is why it's downsizing the cache values. This is all speculation without being able to look at the errors log (during startup). I find it very odd you can not get access to your own logs, it's such a vital part of the server, you should really get that addressed or else we can't really help you :(I would offer logs if I could, but we cannot get them off the system. It is hosted in a disconnected environment.Regards, MarkPaul M.

I am not sure I can attribute this issue to this update since we are now just discovering it. But setting the nsslapd-cachememsize is reverting to a default value of 2GB. I have attempted to restore the value through the console and restarting the instance. I have also tried by stopping instance and manually editing the dse.ldif file.
