Fixed In Version:	389-ds-base-1.3.7.5-26.el7_5
Doc Type:	Bug Fix
Doc Text:	Previously, the nucn-stans framework was enabled by default in Directory Server, but the framework is not stable. As a consequence, deadlocks and file descriptor leaks could occur. This update changes the default value of the nsslapd-enable-nunc-stans parameter to "off". As a result, Directory Server is now stable.

Build tested: 389-ds-base-1.3.7.5-26.el7_5.x86_64

On a fresh instance:
[root@server ds]# ldapsearch -xLLL -D cn=Directory\ Manager -w password -b cn=config -s base nsslapd-enable-nunc-stans
dn: cn=config
nsslapd-enable-nunc-stans: off

[root@server ds]# pstack $(pidof ns-slapd) | grep 'nunc-stans\|ns_' -c
0

Nunc-stans is disabled by default, marking as VERIFIED.
