Fixed In Version: 389-ds-base-1.3.4.0-20.el7_2 Doc Type: Bug Fix
Doc Text:
Previously, when nunc-stans was enabled, the default thread number was 3, and the thread number was controlled by the MAX_THREADS environment variable. With this update, the value of the nsslapd-threadnumber configuration parameter is used instead of obtaining the thread number from MAX_THREADS.

Description Jan Kurik 2015-11-06 10:02:05 UTC
This bug has been copied from bug #1278584 and has been proposed
to be backported to 7.2 z-stream (EUS).

Comment 4 Viktor Ashirov 2015-11-26 22:43:42 UTC
Build tested:
389-ds-base-1.3.4.0-21.el7_2.x86_64

# tail -n1 /etc/profile
export MAX_THREADS=100

nsslapd-threadnumber: 30
nsslapd-enable-nunc-stans: off

# ps huH p $(pidof ns-slapd) | wc -l
41

nsslapd-enable-nunc-stans: on
# ps huH p $(pidof ns-slapd) | wc -l
72


On the older version (389-ds-base-1.3.4.0-19.el7.x86_64):

nsslapd-enable-nunc-stans: off
# ps huH p $(pidof ns-slapd) | wc -l
41

nsslapd-enable-nunc-stans: on
# ps huH p $(pidof ns-slapd) | wc -l
142

Looks like nunc-stans created additional thread pool (30 + 100 + 12 service threads). And on a new version it's 30 + 30 + 12. So the original issue is fixed, so I mark this bug as VERIFIED. For the mentioned issue new bug will be opened.
