Today OOMs were reported on a physical server with 1.5TB of RAM, running SQL Server 2016 SP1 CU4. I started to poke around a bit... pretty sure we'll need to set up perfmon and maybe a SQL agent job to capture numbers every 5 minutes. Capturing the memory clerk numbers seems like the place to be.
Here's the SQL if you want to play along at home. But I'm too sleepy to do anything with it tonight.
