** [tickets:#2530] amfd: amfd coredump after SC absence**
**Status:** fixed
**Milestone:** 5.17.10
**Labels:** assignment failover during stop of both SC
**Created:** Wed Jul 19, 2017 03:00 AM UTC by Minh Hon Chau
**Last Updated:** Fri Jul 28, 2017 08:20 AM UTC
**Owner:** Minh Hon Chau
amfd coredump happens in the same sceario of ticket #2477
In #2477, amfd prevents to create 2 active assignments for same 2N SI, but amfd
has missed a case of 2 standby assignments, which leads to the coredump in this
ticket
