Kaushik, could you please try if killing the sssd_be process (kill -SEGV $(pidof sssd_be)) still hangs the process with 1.11 ?

Comment 3 Kaushik Banerjee 2014-04-24 10:43:49 UTC

Tested on RHEL6.6 with sssd version 1.11.5.1-1.el6.ppc64

I added a (kill -SEGV $(pidof sssd_be) in the automation script. But sssd seems to recover from this forced

Then I would propose to either fix this bug or mark is as fixed with the rebase.

I remember a couple of fixes upstream that were arch-specific (the bool/dbus_bool_t issue comes to mind).

Thank you for testing!

Comment 5 Jakub Hrozek 2014-05-15 11:57:32 UTC

I meant to say 'close' this bug instead of 'fix' earlier. Per comment #3 the recovery is fixed in 1.11.

Kauhshik, can you qa_ack this bug since you alredy amended the automation? Then I would include the bug in the 6.6 errata.

Comment 6 Jakub Hrozek 2014-05-22 10:11:47 UTC

This was fixed in a rebase.

Comment 7 Jakub Hrozek 2014-06-02 08:17:37 UTC

*** Bug 1102874 has been marked as a duplicate of this bug. ***

Comment 9 Kaushik Banerjee 2014-07-09 04:39:18 UTC

Verified with sssd-1.11.6-1.el6.ppc64

sssd recovers from a forced crash.
