and the corresponding R-VOL update reaches the specified time, the RCU will suspend all R-VOLs
in the group. A timeout occurs when the RCU was not able to settle a recordset within the specified
time, or when the RCU has not had any communication from one of the MCUs in the group within
the specified time.

with the RCU within the specified time, the MCU suspends all M-VOLs in the group.
