We upgraded from Samba version 4.15.9 to 4.18.1 on last Saturday. We are 
running AD-DC Service. Our upgrade process was nothing but a fresh 
compile & installation and add the samba instance to AD-DC cluster as a 
Domain Controller and demote and remove the old one. Of 5 server, there 
are no issues. 2 of them experiencing slowness and in the logs we are 
seeing "single_accept_connection: NT_STATUS_TOO_MANY_OPENED_FILES" being 

The smb.conf is a standard auto-generated one. No specific parameter is 
added. This is slowing down the response to Authentication requests, DNS 
queries and even replication.

Any suggestions to correct this issue?


Thanks & Regards,
