I have an instance of SQL Express 2008 running as the backend for a small webapp on a server.
The server specs: Windows 2003, 64bit quadcore, 4gb ram
The SQL database is only 50mb on disk and I have never seen the SQL process use more than 200mb of ram in the task manager but I am noticing these messages related to memory issues in the SQL Logs.
AppDomain 2 (mssqlsystemresource.sys[runtime].1) is marked for unload due to memory pressure.
Any idea what could cause this ?
