Low physical memory alert - no SQL process

On one of my monitored servers I am getting the 'low physical memory' alert, but the alert details does not pick up the fact that SQL is consuming most of the memory:

Low memory detected at 27/04/2009 09:10:05
Other processes were using : 7.2 GB
Free Space: 799.7 MB
Total: 8.0 GB

whereas on another server I get a more meaningful breakdown:

Low memory detected at 27/04/2009 09:08:14
SQL Server was using 6.3 GB
Other processes were using : 866.2 MB
Free Space: 902.2 MB
Total: 8.0 GB


Any reason for not detecting the SQL process?


Server with issue : SQL Server 2005 SP2 + GDR July 2008 (version 9.0.3068)

Server without issue : SQL Server 2005 SP3 (version 9.0.4035)

SQL Response v1.2.0.219
