Hi,
I have a Windows Server 2008R2 with SQL server 2008R2 Standard, it is a virtual machine with 16GB startup memory, 12GB min and 20GB max. It has 5 cores from an Intel Xeon E5645 2,4GHz to work with.
The problem I am having is that the SQL server sometimes becomes very slow or even unresponsive to querys and the only way to get it running normal again is a reboot. When I look at the memory on the VM in Task manager it says it is using 16GB but if I look at the VM-host it says that the assigned memory is only 12GB and the memory demand is even less so it does not seem to be out of memory...
The VM-host is a Server 2012.
I need some help in trying to locate the culprit that is causing this problem because I cannot see any errors or warnings in the Windows event log or the SQL server log. So any suggestions would be greatly appreciated :)
