** [tickets:#2105] AMF : SG is unstable, if app responds during node link loss
detection time period**
**Status:** assigned
**Milestone:** 5.2.RC1
**Created:** Sun Oct 09, 2016 07:12 AM UTC by Srikanth R
**Last Updated:** Sun Oct 09, 2016 07:12 AM UTC
**Owner:** Minh Hon Chau
Setup :
Changeset : 8190
5 node SLES setup with 2 controllers and 3 payloads ( TIPC -- headless enabled)
2n application deployed on 2 payloads.
Issue :
-> Perform admin operation on an AMF enity.
-> Do not respond to the callback and invoke headless scenario.
-> On a VM with TIPC setup, 3 seconds is taken to detect the node down.
-> If the application responds to a callback in admin operation during this
time period when the last controller is down, the message shall not reach any
controller. Amfnd on payload shall send the "Assigned" message but not store
this message.
For this scenario, SG shall move to unstable state. Below is the snippet from
syslog, where application responded at 15:48:28 and at 15:48:31 payloads
detected that last controller is down.
