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.

Comment 2 Jakub Hrozek 2012-12-05 14:15:57 UTC 
Is it possible to get a corefile or a backtrace with abrt, for example?
Comment 3 Taunus 2012-12-05 14:26:04 UTC 
It is some child process crashing.. How do I get a corefile or backtrace? sssd prints out these over and over:

(Wed Dec  5 16:24:12 2012) [sssd] [monitor_quit] (0x0010): [10][No child processes] while waiting for [pac]
Comment 4 Jakub Hrozek 2012-12-05 14:51:23 UTC 
(In reply to comment #3)
> It is some child process crashing.. How do I get a corefile or backtrace?

yum install abrt
service abrtd start

should do the trick.

That's an unrelated bug fixed in a later build.
Comment 5 Jakub Hrozek 2012-12-06 09:38:25 UTC 
Oh, I think I know what's going on. Can you try manually setting ldap_sasl_authid ?

I bet you're hitting #877972

Yes, setting the option in sssd.conf helps.
