> Agent's rogue process detector should change to detect a process that is defunct. Its been observed that a process drops core and remains running as defunct. Since it is up, the agent is happy and keeps reporting the process as Running. 
> Trying to kill via kill -9 doesnt help. It looks like the defunct process must be be cleaned up by root. 
> Modify code to change the state of such process from Running to Defunct (?).
