System.Data.Dat aSet on Hyperthreading CPU issues ...

[octaviansen]

Hi,

I am experiencing some weird problems with an ASP.NET web application
that is making use of System.Data.Dat aSet and System.Data.Dat aRow
classes.

On a machine with single CPU, the application is running fine.

On a machine with Hyperthreading CPU, after a couple of seconds of
running OK, the
application is crashing and the stack dump indicates that the error
appears when trying to write in a System.Data.Dat aRow object.

If I am disabling the CPU Hyperthreading feature the application runs
OK also on this machine.

Did anyone experienced also issues like this ?

Here it is the stack dump:

Source Error:
Line 1834: }
Line 1835: set {
Line 1836: this[this.tableSubsc ription.Require dStatusColumn] = value;
Line 1837: }
Line 1838: }

Source File: c:\inetpub\wwwr oot\CDS\DectDat aSet.cs Line: 1836
(My note: this file is auto-generated from an XML schema file)

Thanks is advance to anyone that can provide me some information in
order to address this issue.
