The error message that you will see in the session log is unpredictable, but it will often look something like this:
[Major] From: BSM@cellmgr.ifost.org.au "IFOST backup" Time: 9/11/2015 1:18:44 PM
[61:3003] Lost connection to B2D gateway named "DataCentrePrimary"
on host storeonce.ifost.org.au.
Ipc subsystem reports: "IPC Read Error
System error:  Connection reset by peer
One of the ways of detecting the problem was that the command "StoreOnceSoftware --list_stores" would hang.
I created the following three batch files and scheduled CheckStoreOnceStatus.cmd to run once per hour:
start /b CheckStoreOnceStatusController.cmd
start /b CheckStoreOnceStatusChild.cmd
waitfor /t 600 fiveminutes
WAITFOR /SI StoreOnceOK
WAITFOR /T 30 StoreOnceOK && (
REM StoreOnce OK
REM StoreOnce failure
net stop StoreOnceSoftware
waitfor /t 120 GiveItTime
net start StoreOnceSoftware
Actually, I also added a call out to blat to send an email after the net start command.
So, CheckStoreOnceStatus spawns off *Controller, which will wait for 30 seconds for a signal to arrive from *Child as soon as child has been able finish StoreOnceSoftware --list_stores.
