Since upgrading from SQL Server 2008 Enterprise to SQL Server 2012 Core on a 4 socket, 8 core system we are experiencing large drops in PLE across the 4 NUMA nodes and/or large flucations on individual NUMA nodes. This occurs during the quietest periods on the system with a min memory setting of 80GB and a max memory setting of 112GB. There is no internal or external memory pressure on the system when this occurs.
