SSIS And NUMA

SQL Sasquatch has some SSIS package issues stemming from a lack of NUMA awareness:

So the server had plenty of free RAM.  But NUMA node 1 was in a pinch.  And SSIS spooled its buffers to disk.  Doggone it.

I guess I’d figured that notifications were sent based on server-wide memory state.  But I guess maybe memory state on each NUMA node can lead to a memory notification?

The target SQL Server instance, a beefy one, was also on this physical server.  There’s 1.5 TB of RAM on the server.  🙂

It also looks like the easiest fix is something which was deprecated in Windows Server 2012 R2.
