** [tickets:#1828] AMF: Both director and node director hang if immnd dies in
new SC reallocation scenario**
**Status:** fixed
**Milestone:** 5.1.FC
**Created:** Mon May 16, 2016 05:29 AM UTC by Minh Hon Chau

Enable cloud & roaming feature.
If both Active and Standby SC are stopped at the same time, new controllers
will be allocated to be Active/Standby. During this new Active role allocation,
if immnd dies there will be circle dependencies in controller (who is going to
be Active):
- clmd can not use IMM services since immnd dies
- immnd needs restarted by amfnd
- amfnd is hanging since amfnd is calling CLM services
- amfd is also hanging since amfd is calling CLM and NTF services
- ntfd is hanging due to logd's dependencies on IMM
The problem can be solved if amfd/amfnd are not blocked in main thread so immnd
can be restarted and controller will not be reboot due to heartbeat time out
