The Survivable Processor object monitors keep-alive message between the main server and the survivable processor, which can be either:
Survivable Remote Server
Survivable Core Server
The server exchanges keep-alive messages with each of the survivable processors. If the server does not receive a predetermined number of those messages, both the server and the survivable processor alarm.
Possible causes for SP-REG-S alarms include:
The network is down.
The server or survivable processor administration is incorrect.
