ManagementObjectSearcher sin memoria exceptiton

Question

En una aplicación C# .Net MVC2 tenemos una función simple para obtener la id del procesador como parte de un esquema para identificar el servidor web. La parte relevante es:

using (ManagementObjectSearcher searcher = new ManagementObjectSearcher("select ProcessorId from Win32_Processor")) 
     { 
      foreach (ManagementObject share in searcher.Get()) 
      { 
       foreach (PropertyData PC in share.Properties) 
       { 
        return PC.Value.ToString(); 
       } 
      } 
     } 

ha funcionado bien en dev y en una serie de servidores web que ejecutan cassini e IIS. Sin embargo, en la última instalación en una máquina de Server 2008 se lanza una Excepción de falta de memoria en la primera llamada para obtener la id del procesador. Cualquier consejo sobre una posible causa o mejor forma de lograr lo anterior.

Muchas Gracias

Me acabo de encontrar con un problema similar, intentar consultar Win32_Service. Fui a la consola WMI bajo Administrative Tools\Computer Management. La pantalla principal mostró un error de falta de memoria para Win32_Process. Terminé reiniciando el servicio WMI ("Windows Management Instrumentation") y eso solucionó el problema.
