Hi,
These errors are likely coming from nis plugin. NIS plugin and
Schemacompat plugin are sharing code. To prevent SchemaCompat deadlock a
new locking mechanism was introduced. This new mechanism is initialized
by SchemaCompat init function. So if SchemaCompat is not
enabled(initialized) and NIS plugin is enabled, NIS detects that new
locking mechanism is not available and fall back to the old one.
NIS plugin should work normally except those alarming logs.
The BZ is not fixed yet. If NIS plugin keeps enabled, a way to
workaround this BZ is to enable schemaCompat as well.
best regards
thierry

I’ve started getting a lot of messages in 389-ds errors log - so many, in fact, that /var/log filled up and 389-ds stopped running. Has anyone ever seen anything like this? Any idea what to do about it? It’s been mentioned to me that schemacompat comes from FreeIPA. I'm not running FreeIPA, but do have some IPA-related packages installed which I've never done anything with. I’m running 389-ds-1.3.9.1-10.el7.x86_64 on CentOS 7.6.1810.
