no PBE )
AMF Application : NPM model with SUs mapped on SC-2,PL-3,PL-4

Summary :
AMFD on both controllers asserted, if Nway application failed in CSI SET 
QUIESCED callback in lock operation of node group 

Steps followed & Observed behaviour

-> Hosted nway application on PL-3,PL-4 and SC-2 and brought up the 
application. Configuration is attached to the ticket.

-> Ensured that one of component will not respond to quiesced callback
-> Now performed the lock operation on the node group
-> amfd on both controllers asserted with the following back trace.
