SAPStructure.GetSAPFieldsSchema

Question

Hi,
I use the SAP.Connector 2.0 in a Windows 2003 SP1 environment and SAP R/3 6.20.
In this case I want executing the same RFC in two different SAP environments from WebService ASP.Net.
The client is a ASP application and communicate with the WebService through SOAP Toolkit 3.0.
The problem happens when the first RFC failed, the following request it fails again, this problem only it solves when recicle the app pool of Webservice.
The error happens when my code execute SAPStructure.GetSAPFieldsSchema(type)
Where "type": Is the type structure of specific table.
When analyzing the problem I believe that this function implement some type of caché.
What is the function of this cache?
They know like disabled that cache?
If is disabled, it affect the request performance?
Thanks in advance.
Sergio.

E.g
proxy.Z_Hrpfpa00105("XX", "45", out sts, ref tIVAEmp);
Type structureType = tIVAEmp.GetElementType();
SAPField[] fields = SAPStructure.GetSAPFieldsSchema(structureType);
foreach (ZHRRESNOM row in tIVAEmp)
  foreach (SAPField field in fields)
    Console.WriteLine("{0}: {1}", field .FieldName, row[field.FieldName]);
Accessing fields by name may be a little bit slow. Alternatively you can access it by index, which is faster:
  for (int i=0; i<fields.Length; i++)
    Console.WriteLine("{0}: {1}", fields<i>.FieldName, row<i>);
