Spectrum switching to secondary, during OLB causing SANM policy change

Issue/Introduction
Periodically, during the Online backup on the Primary SpectroSERVER, management will switch over to the Secondary SpectroSERVER causing SANM to revert to a different policy.
When an alarm occurs during this time, notification is sent out incorrectly.
Cause
The cause of the problem is Notifier is loosing the connection with Primary - mostly because primary becomes un-responsive.
The perfCollector shows that the available memory keeps dropping and SpectroServer uses very low memory.
The SpectroServer was installed on a Virtual Machine and the memory was shared.
When Notifier looses the connection with primary, it will establish a connection with Secondary.
Environment
Release : 10.3
Component : Spectrum Core / SpectroSERVER
Resolution
We document dedicated resources for SpectroSERVERs installed on virtual machines.
This is because Spectrum is a real time application and will suffer unexpected side affects with shared memory.
