(yet) (Tue Jan 26 19:21:33 2016) [sssd] [tasks_check_handler] (0x0020): Child (foo.local) not responding! (yet) Thouroughly confused now.. I thought I had the above issue pinned down on IBM Java; http://www-01.ibm.com/support/docview.wss?uid=swg1IV71405 IV71405: JGSS CANNOT GET KDC FROM DNS. but now I also see this; https://bugzilla.redhat.com/show_bug.cgi?id=966757 SSSD failover doesn't work if the first DNS server in resolv.conf is unavailable Seems both the above links are issues with reading and using DNS whether it is caused by SSSD or IBM Java ibmjgssprovider.jar. I am not running the version of sssd that in the bugzilla post but.. ipa-python-3.0.0-42.el6.ppc64 libipa_hbac-1.11.6-30.el6_6.4.ppc64 sssd-ipa-1.11.6-30.el6_6.4.ppc64 ipa-client-3.0.0-42.el6.ppc64 device-mapper-multipath-0.4.9-80.el6_6.3.ppc64 CPU spike to 100% for SSSD and requires a reboot or interestingly enough a kill -9 java process. Kinit also does not work on the box with: com.ibm.security.krb5.KrbException, status code: 0 message: Cannot find KDC for realm foo.LOCAL Also .. the box has been running fine for a couple of months with kinit not working. The kinit issue is the IBM APAR and I am working with IBM java for a new ibmjgssprovider.jar but the sssd cpu spiking to 100% is so random and all over the place. Not sure if I am dealing with 2 issues or 1 issue here. I am thinking 2 issues with kinit being ibm java.. and cpu 100% being sssd issue. Systems are set for dns lookup in krb5.conf Sean Hogan Security Engineer
