The rule triggers an alert when SQL Server failes to create an application domain manager
SQL Server failed to create an application domain manager. This may be caused when there is not enough memory to start the application domain.
When memory resources are too low an application will not be able to create an AppDomain.
Verify that there are no hardware issues. Check Windows system and application logs to identify errors related to system stress or memory. Increase the amount of available memory. Consider the following solutions to increase available memory:
Increase the size of the paging file.
Restart the server with the -g memory_to_reserve option to increase the amount of memory that SQL Server will leave available for memory allocations within the SQL Server process.
Add physical memory. On a 32-bit system you can add more than 4 GB physical memory if you use Microsoft Windows Address Windowing Extension (AWE).
Restart the computer and run again. If the problem persists, contact a product support provider.
