It was ported from a running OpenLDAP environment to IPA. Just trying
to do conversions in stages so as not to change too much all at once.
Thought I could go from OpenLDAP to IPA and just use the backend of
389ds. Functionally it does work, but the load kills it. Seems like
FDs are a huge problem. But all the settings documented don't see to
resolve the magic:
Ok. This is yet a third issue - 1) crashes 2) high cpu 3) running out

Shouldn't this increase file descriptors in conjunction with
/etc/sysconfig/dirsrv.systemd change? FS-limits across the OS are set
to 65535 - /etc/security/limits.conf, /proc, sysctl.conf -- everything
but 389-ds itself. But I still can't get this to work, although it
does not give an error.
ldapmodify -x -D "cn=directory manager" -W <<EOF
dn: cn=config,cn=ldbm database,cn=plugins,cn=config
Note that nsslapd-maxdescriptors: 65535 is extremely high. I would not
suggest going over 8192.

BTW - a bit of information others might find useful. If you try to

That should not happen.
For crashes, we would need to look at some stack traces:
For situations when the CPU is through the roof, that is very similar
to debugging hangs:
Sorry, forgot to mention that since this is IPA you'll also need to
install the ipa-debuginfo and slapi-nis-debuginfo packages.
I would also add a question about your client configuration.
For example if you use SSSD with enumerate=true for your clients then
yes you will get your environment to the knees pretty quickly.
I assumed SSSD wasn't being used at all which begs the question: what
is? nss_ldap? Is nslcd being used?
What is hitting LDAP, only auth or something else (e.g. sudo, automount).
Since IPA is supposed to handle all options, I guess I am
