RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Aleksandr Sharov 2022-11-29 10:19:52 UTC 
Created attachment 1928235 [details]
debug sssd logs

Description of problem:
After severe load on the system, including oom state, sssd's dbus looses ability to talk with it's data providers:

   *  ... skipping repetitive backtrace ...
(2022-11-26 12:18:08): [be[default]] [dp_client_handshake_timeout] (0x0040): Client [sssd.pam] timed out before identification [0x55cc9111b620]!
   *  ... skipping repetitive backtrace ...
(2022-11-26 12:18:08): [be[default]] [dp_client_handshake_timeout] (0x0040): Client [sssd.nss] timed out before identification [0x55cc91118770]!

This state remains until the sssd service is restarted.


Version-Release number of selected component (if applicable):
RHEL 8.6, sssd-2.6.2-4.el8_6.x86_64

How reproducible:
Couldn't reproduce the state in the lab. In client's environment, it's happening every 24 hours when custom cron script is running.

Steps to Reproduce:
1.
2.
3.

Actual results:

SSSD state is not recovered automatically

Expected results:

SSSD continues to work as expected after the system is out of heavy load and/or OOM.

Additional info:

Debug logs attached (nss trimmed to last 2000 lines, full logs in case). Issue happened around 5:39-5:41 AM , difficult to distinguish better because system appears to be hang at the time.

Additional data and sosreport are in the attached case.
