Most of the client memory is in page cache, which is entirely normal and even improving the buffering on the server wont prevent aggressive caching of this data client side. Have you tried flushing the page cache (...

No, forcing use of less memory is likely to make things slower, not faster. You are spending power on 188 GB of fast DRAM already, might as well use it. Client host has 188 GB MemTotal, and is using 162 GB of it for Cached. Actually quite low on the memory demands, note 123 GB MemAvailable that can be freed very quickly. Most of the 40 GB of Shmem is ...

The solution in my case was the following: I tried making LDAP DB on my production DC look like LDAP DB on the fresh DC (which is working). So I changed some fields. Rebooted everything. And it worked! What I changed exactly. I added/changed the following fields in the object dn: DC=my,DC=domain using ldbedit -H /var/lib/samba/private/sam.ldb: msDS-Behavior-...
