RSRB State

Open with no problem:

closed          -->          opening
opening         -->          openwait
openwait        -->          remwait
remwait         -->          remgo
remgo           -->          draining
draining        -->          open

Open with no success (the TCP/IP connection is bad):

open            -->          closed
closed          -->          opening
opening         -->          openwait
openwait        -->          dead

Open with no success (one configuration with fst, the other configuration with TCP):

closed          -->          opening
opening         -->          openwait
openwait        -->          remwait
remwait         -->          openwait
openwait        -->          remwait
remwait         -->          openwait
openwait        -->          remwait
remwait         -->          openwait
openwait        -->          remwait
remwait         -->          dead

dead        RSRB_PS_DEAD = 0,        /* temporarily shutdown */
closed      RSRB_PS_CLOSED,          /* no activity */
opening     RSRB_PS_OPENING,         /* waiting for connector */
openwait    RSRB_PS_OPENWAIT,        /* waiting for transport open */
remwait     RSRB_PS_REMWAIT,         /* transport open, waiting for rsp*/
remgo       RSRB_PS_REMGO,           /* remote said do it */
remopen     RSRB_PS_REMOPENED,       /* remote opened before we did */
