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.

Fixed In Version: sssd-1.2.1-28.el6_0.3
Doc Type: Bug Fix
Doc Text:
During an upgrade of the sssd package, the package manager restarts the sssd service to ensure the running instance is properly replaced with the newer version. However, prior to this update, a race condition could occur upon the service shutdown, causing the parent process not to wait for its children to terminate. When this happened, these running sub-processes may have prevented sssd from starting again. With this update, the sssd service has been corrected to wait for the children processes to terminate, so that it can be restarted as expected.

Description of problem:

When sssd is upgraded, it gets shut down but is not restarted.  My upgrades are done via yum-cron.

Just happened again with sssd-1.3.0-32.fc13.i686

--- Additional comment from sgallagh on 2010-10-04 09:22:59 EDT ---

Sorry, I forgot to port forward the fix for this to F13 and F14.

Correcting it now. Please be aware that the upgrade to the fixed version may still abort because the problem was with the %post section of the specfile. This means that the old package will still execute its version of this code, not the fixed RPM.

However, future updates should not have the same problem.

Today sssd-1.3.0-35.fc13.x86_64 has been installed here on serveral hosts
AND did not start again afterwards:

Please read the updated notes. The problem is in the %post section of the previous version. This means it gets run at upgrade or removal, regardless of whether the new version corrects the problem.

The changes I made in sssd-1.3.0-35.fc13 were meant to prevent this problem from happening in future updates. There's nothing I can do about versions earlier than the current one, unfortunately.

--- Additional comment from gasi.de on 2010-10-12 08:34:03 EDT ---

Sorry - I read your comment #7 too late.

# rpm -Uvh --force .../sssd-1.3.0-35.fc13.x86_64.rpm

actually works and sssd is still/again running. Seems to be ok now.

Updating from sssd-1.3.0-35.fc14 to sssd-1.4.0-2.fc14 resulted in sssd not running after update, which was supposed to be fixed in 1.3.0-35.fc14.

--- Additional comment from orion.com on 2010-11-03 11:21:44 EDT ---

Again with 1.4.0-2.fc15 -> 1.4.1-1.fc15.

sssd-1.3.0-36.fc13.x86_64 did not come up automatically after being
installed on 8 out of 17 machines - the others 9 ones are ok:

It is getting better - but I am not content, but maybe it is another fault:

This is caused by https://fedorahosted.org/sssd/ticket/555, I think.

I am working on a patch for this problem as we speak. Hopefully I will have a fix for this particular issue in the next day or so.
