Hi Thuan,

Thanks for your comment.
First this issue happen only in specific situation. And I think restart it is 
no cause big issue.
And the ccb is internal data based mange by ntf/ntfimcnd. After ntfimcnd 
restart, it reinitialize 
CcbUtilCcbData and operation invoke name is empty.

Moreover, in current code in ntfimcn_imm.c, there are many place use 
imcn_exit(EXIT_FAILURE)
when detect the error. Example for this is #2859.
We consider to open a new ticket to consider your suggestion by refactor/change 
current behavior of ntfimcnd.

B.R/Thang

Hi Thang,

The point is why we cannot get admin owner or object implementer via 2nd imm 
modify callback in this scenario?
Is it an IMM limit that don't include admin owner or object implementer from 
2nd modify callback?

If limit, can we use another way to get admin owner or object implementer base 
on object name?
By this, we can avoid continuous exit if user keep going on operations by same 
CCB.

Best Regards,
ThuanTr

name [#3178]

If ntfimcnd is restarted during ccb modify, it will initialize ccbUtilCcbData 
that not contain operation invoke name.
This causes ntfimcnd crashed due to operation invoke name not existed.

The fix is to restart ntfimcnd instead of raising the coredump.
