** [tickets:#2210] AMFD: Loss of RT attribute update before headless**
**Status:** unassigned
**Milestone:** 5.2.FC
**Created:** Mon Nov 28, 2016 10:18 PM UTC by Minh Hon Chau
**Last Updated:** Mon Nov 28, 2016 10:18 PM UTC
**Owner:** nobody
A loss of IMM RT saAmfSIAdminState update in AMFD has been seen just before
cluster goes headless. It results in coredump after headless.
One scenario is:
- Issue amf-admin shutdown SI, delay csi quiescing callback
- Stop SCs, release csi quiescing callback
- Restart SCs
Observation: the saAmfSIAdminState is read as UNLOCKED while related SUSI was
QUIESCED, and coredump as below
