Upstream ticket: https://fedorahosted.org/389/ticket/48925 We have decided not to support nunc-stans on this specific hardware. It's old, and all modern hardware supports the cx16 flag. We will now detect and raise a warning with dsktune for this. Build tested: 389-ds-base-1.3.5.10-5.el7.x86_64 During the initial setup by setup-ds.pl dsktune is executed and the following message is showed to the user: [root@mgmt8 ~]# setup-ds.pl ============================================================================== This program will set up the 389 Directory Server. It is recommended that you have "root" privilege to set up the software. Tips for using this program: - Press "Enter" to choose the default and go to the next screen - Type "Control-B" or the word "back" then "Enter" to go back to the previous screen - Type "Control-C" to cancel the setup program Would you like to continue with set up? [yes]: ============================================================================== Your system has been scanned for potential problems, missing patches, etc. The following output is a report of the items found that need to be addressed before running this software in a production environment. 389 Directory Server system tuning analysis version 14-JULY-2016. NOTICE : System is x86_64-unknown-linux3.10.0-464.el7.x86_64 (4 processors). ERROR: This system does not support CMPXCHG16B instruction (cpuflag cx16). nsslapd-enable-nunc-stans must be set to "off" on this system. In a future release of Directory Server this platform will NOT be supported. NOTICE : The net.ipv4.tcp_keepalive_time is set to 7200000 milliseconds (120 minutes). This may cause temporary server congestion from lost client connections. WARNING: There are only 1024 file descriptors (soft limit) available, which limit the number of simultaneous connections. ERROR : The above errors MUST be corrected before proceeding. Would you like to continue? [no]: Marking as VERIFIED.
