Description of problem:
Client is trying to implement a HBAC rule for a big host_group - around 2500+ hosts.
After trying to add a bunch of new hosts to the group, IPA hangs for some time, possibly because it tries to iterate all memberof plugin tasks.
After some time - after adding 1000 hosts to a 1000 host group it was around 1 hour - the IPA becomes responsive back. The IPA's host systems are intact all the time.
We've tried to capture strace of dirserv, sosreport and atop from the system, you can find them in the case attached.
Version-Release number of selected component (if applicable):
389-ds-base-1.3.10.1-14.el7_8.x86_64 Mon Aug 31 23:07:33 2020
ipa-server-4.6.6-11.el7.x86_64 Mon Aug 31 23:08:07 2020
RHEL 7.8
How reproducible:
- not enough hosts in lab env to reproduce
Actual results:
IPA is hung fro long time and can't serve clients at all
Expected results:
IPA remains responsive, or processing takes significantly less time
