Resolution:
The command, "kill pid <process_id>", will gracefully bring down an RV daemon. If started with the -foreground option, an RV daemon will exit via a Ctrl-C via Sigint. We do not recommend using “kill -9 <process_id>” to shut down an RVD process.

An RVD daemon will gracefully shut down only if it receives one of the following signals:

1).  SIGINT (Signum 2)
Sent through kill -2 <pid> or by ‘<ctrl> c’

2). SIGTERM (Signum 15)
Sent through “kill <pid>” or by “kill -15 <pid>”

RVD may not gracefully shutdown through any other method. e.g., kill -9 <process_pid>.
