Hi All,
I'm running SQL 2014 SP3 and after July 2019 patching I'm seeing lots of errors relating to memory issues i.e. There is insufficient system memory in resource pool 'internal' to run this query
This is causing alot of problems executing basic queries and backups are failing
The server itself has plenty of available memory and max memory is set to 65 GB. I noticed from a monitoring tool that we use we observed and a severe degradation in the maximum workspace memory and a massive increase in pages allocated to memoryclerk_SOSNODE. This all occurred after installed July 2019 updates KB4504418, KB4507448, KB506996 & KB507005
Do you think the updates have caused a memory leak, We are planning to install SP3 CU3 later this week
Below is the output from DBCC MEMORYSTATUS
