SYMPTOMS
The W3wp.exe process causes 100% CPU utilization on a Microsoft Operations Manager (MOM) 2005 Management Server in the destination management group. Product connectors that are accessing the MOM Connector Framework may receive the following exception error message:

System.Web.Services.Protocols.SoapException: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.InvalidOperationException: There was an error generating the XML document. ---> System.ArgumentException: The surrogate pair is invalid.

After these symptoms occur, data is not forwarded from the management group. W3wp.exe is a worker process for Microsoft Internet Information Services (IIS).



CAUSE
This problem occurs if the following conditions are true:
 * A MOM 2005 product connector uses the MOM Connector Framework from multiple management groups.
 * The MOM 2005 product connector is configured to forward discovery data to the destination management group.
 * The W3wp.exe process is running on the MOM Management Server.

Another problem with the MOM Connector Framework occurs if the error message description includes special characters or invalid characters.
