Hi all!! and after all, sorry for my english!!! We have a memory problem, that I don't know how to solve. We have a Windows Server 2008 Enterprise with 8 cores and 32Gb of RAM. We assign 20GB to SQL Server, an there is 12 GB free for OS. Basically the problem is that Windows Server is out of memory. For example statistics (we have to restart the server to get it normal again): Total Memory 32GB Used for SQL Server 20GB Cached memory 10GB What means that, the OS use this memory??? Free Memory 512MB !!!!!!!!! I don't know what means Cached Memory for Windows Server, but when we get out of memory the performace of the server is very bad. I ask here becouse, I thinks there would be someone who got the same problem, but i will ask in a windows server forum too. Thanks for all!!! and sorry for my english
