**Status:** review
**Milestone:** 4.7.2
**Created:** Tue Apr 19, 2016 06:53 AM UTC by Srikanth R
**Last Updated:** Wed Jun 08, 2016 11:26 AM UTC
**Owner:** Praveen
Setup :
5 node cluster with 3 payloads
changeset : 7438 ( opensaf 5.0.FC)
Application : 2N with 5 SUs ( si-si deps enabled & su failover flag enabled)
Issue :
AMFND hosting the faulty SU segfaulted during su Failover escalation as part
of SU lock operation
Steps performed :
-> Initially bring up the application and ensure that application is fully
assigned.
-> Perform one fault operation on the SU hosting the active assignment, such a
way that the next fault is escalated to su failover.
-> Perform lock operation of SU hosting the active assignment.
-> Do not respond to the CSI removal callback, for which this fault shall be
escalated to su failover.
-> AMFND seg faulted with the following bt file
