I have noticed this error occasionally in the SQL error log:
spid20s,Unknown,AppDomain 79 (master.sys[runtime].78) is marked for unload due to memory pressure.
I am using SQL Server 2016, SP1 CU5 (I am pushing for patching but the company is resistant).
Everything I have read points to non-CLR-specific memory pressure. There are suggestions around changing the
MemToLeave setting in the start up parameters. Is this still the case for newer versions of SQL Server, or are there other recommendations?
