This read-write Integer32, in milliseconds from 0 to 600000, sets the maximum waiting delay (MWD) used to randomly seed the restart timer a gateway starts on power-up, sending its first Restart In Progress (RSIP) message to the MGC when that randomized timer expires. Admins care because this randomization prevents many gateways from flooding the MGC with RSIP messages simultaneously after a shared power event. For example, an admin managing a rack of gateways that reboot together after a power outage would rely on this MWD spreading their RSIP notifications out over time.
