Analysis:
For the CSI4, CStype is safVersion=4.0.0,safCSType=AmfDemo1 and for the rest
of CSIs it is safVersion=4.0.0,safCSType=AmfDemo. Now CSI4 directly or
indirectly acts as sponsor for CSI3, CSI6,CSI7,CSI8,CSI9 and CSI10. FOr CSI4
compcstype is not configured in the configuration. So AMF deletes compcsi for
CSI3, but since there is chain of dependency, all other compcsi could not be
deleted because logic of deleting COMPCSI
(verify_csi_deps_and_delete_invalid_compcsi() in sgproc.c in #387) assumes
that a SI (like SG) keeps the list_of_csi in the order of rank. On closely
examining the function AVD_SI::add_csi_db(), the intention it seems is to
arrange the CSIs in a SI in the order of rank. But this function is not doing
that. I tried a small patch

all things worked fine.
However the problem can also be solved by accommodating this fact in
verify_csi_deps_and_delete_invalid_compcsi() itself. In this cat a patch will
be required to make recursive call to this function whenever one compcsi is
deleted.

** [tickets:#1333] AMF: amfnd segfaults on controllers during opensafd
shutdown**
**Status:** accepted
**Milestone:** 4.5.2
**Created:** Wed Apr 22, 2015 04:02 PM UTC by Srikanth R
**Last Updated:** Wed Apr 22, 2015 04:03 PM UTC
**Owner:** Praveen
Changeset : 6377
Attached is the xml configuration with which opensafd is configured for 6 nodes
and one 2N application ( two SUs hosted on each of the controller). Cluster
startup timeout is set for 120 seconds
* Brought up opensafd on all the nodes from SC-1, SC-2, PL-3 to PL-4.
* After expiry of cluster timer, the assignments are done to both the SUs
* After some time, stopped opensafd on the payloads, followed by controllers.
* Amfnd seg faulted on both the controllers during shutdown of opensafd
Core was generated by `/usr/lib64/opensaf/osafamfnd --tracemask=0xffffffff'.
