Stolen Server Memory and Database Cache Memory I have the same behavior in 2 SQL Servers where Stolen Server Memory and Database Cache Memory counters are decreasing (Db Cache) and increasing (Stolen Memory) in a linear way. The amount of memory decreased from Db Cache Memory is almost the same amount of memory increased in Stolen Memory.
Has anyone seeing this behavior before? Is it an expected behavior? 

Both server's configuration:


SQL Server 2012 ENTERPRISE with SP3
32GB memory


Thanks for the attention
"stolen" memory?  I like that.  Seriously though, I think the question may be clearer with OS vs SQL memory.  SQL will use the startup minimum set up in the config.  If you didn't set a maximum, then it will continue to steal memory as more work is demanded.

Thus the available total RAM for the OS decreases over time.  Simply set a maximum in the SQL properties, in your case 28GB, so it doesn't steal everything and starve the OS.

This is how SQL behaves normally so it's not that much of a thief.  Hope that helps.
