This alert gets triggered when the IDSReplicationFailure alarm with alarm number 31 occurs, which
invokes a proactive procedure to avoid denial of service. This procedure does not impact call processing;
you can ignore replication alarms during this process.
The procedure takes up to 60 minutes to finish. Check that RTMT replication status equals 2 on each
node to make sure that the procedure is complete. Do not perform a system reboot during this process.
