I'm running SQL Server 2008 on Windows Server 2003 Standard with 4GB of Memory. I'm getting the following error after the system has been running for about 30 hours. There is insufficient system memory in resource pool 'internal' to run this query. This started back in October and took us two weeks to stop. The system used to have SQL Server 2008 and 2005 running on the same box. To stop the issue in October we removed SQL Server 2005 and the issue went away. After a planned power outage on 11/30 the issue return on 12/1 and has been happening ever since. I have add justed the memory allocated to SQL to 3072 and 2661 but it stills keep happening. I have also stopped all backups with no good results.
