| This is not really an issue. SQL Server is designed to work this way. As the server needs more memory, SQL OS grabs more and more memory, until it reaches the maximum you have set. Once it gets to that point, it won't grab anymore, but, if the workload reduces, SQL OS won't release the memory back to Windows OS either. It will hold on to the memory. In other words, SQL OS does its own memory management with the memory you allow it to take.In Perfmon or task manager, you may see SQL taking up a little bit more memory than the max you set. That is because the max you set is the max for buffer pool and not the total memory SQL OS is allowed to take. |
