Hi Ritu Raj,
The problem in #1828 happened in this scenario
- Stop both Active/Standby controllers
- The Quiesced controller will become new active
- The services hang if IMMND is dead during new Active controller
initialization. Simulated IMMND's deadth by killing IMMND process, by I was
doing this way:
diff --git a/osaf/services/saf/cpsv/cpnd/cpnd_init.c
b/osaf/services/saf/cpsv/cpnd/cpnd_init.c
--- a/osaf/services/saf/cpsv/cpnd/cpnd_init.c
+++ b/osaf/services/saf/cpsv/cpnd/cpnd_init.c
@@ -576,7 +576,7 @@ void cpnd_main_process(CPND_CB *cb)
SaClmCallbacksT gen_cbk;
LOG_NO("Bad CLM handle. Reinitializing.");
-
+ if (system("pkill osafimmnd"));
// @TODO figure out why CLMS is not 'instantly'
ready
usleep(100000);
Thanks,
Minh

** [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
