Apologies..

My subject line was "SSSD not starting" but posted it to the old address. Made a new email with the info and copy paste must have dropped it

Hi All,

We are having an issue performing RHEL 6.6 to 6.7 upgrade with SSSD. The systems are already enrolled and working in IPA 3.0.0-50 using 6.6 client. We yum update and sssd gives this

Non-fatal POSTTRANS scriptlet failure in rpm package sssd-1.12.4-47.el6_7.8.ppc64
warning: %posttrans(sssd-1.12.4-47.el6_7.8.ppc64) scriptlet failed, exit status 1

Seems to install however sssd will no longer start. I can run ldap searches against the IPA server and kinit without issue
I have un-enrolled the client and re-enrolled to no avail... once enroll gets to starting sssd it says sssd restart failed and continues to enroll.
I have reinstalled sssd, ipa client and c-ares, I have removed the sssd cache db.


The really strange part is if we wait approx 24 hours sssd starts working again which we have reproduced on 2 servers we are testing with... are we missing some sort of lease or cache? Using this to remove the sssd db
rm -rf /var/lib/sss/db/*




Here is a piece of the gdb core dump

Any help is appreciated as I have spent a good 15 hours reading the logs and bug reports and not any closer to a resolution.
