IntroductionThis article describes an update package for the Microsoft .NET Framework 2.0 Service Pack 1 (SP1). Additionally, this article describes some problems that are resolved by this update package.
This update package fixes the following issue:
- 946660 FIX: The headers attribute of a cell is rendered incorrectly when the cell is associated with multiple headers in an ASP.NET 2.0 Web application
- If the computer is a domain controller and does not have the World Wide Web Publishing Service (W3SVC) installed, an Error event that resembles the following is logged in the event log every several seconds:Event Type: Error
Event Source: Perflib
Event Category: None
Event ID: 1008
The Open Procedure for service "ASP.NET" in DLL "C:\WINNT\Microsoft.NET\Framework\v2.0.50727\aspnet_perf.dll" failed. Performance data for this service will not be available. Status code returned is data DWORD 0.
0000: 05 40 00 80
- If Internet Information Services (IIS) uses the StaticFileHandler class to serve a large file, you may receive the following OutOfMemoryException exception:
System.OutOfMemoryException in System.Web.HttpResponseUnmanagedBufferElement..ctor()
Insufficient memory to continue the execution of the program.
System.Web.HttpWriter.BufferData(Byte data, Int32 offset, Int32 size, Boolean needToCopyData)
System.Web.HttpWriter.WriteFromStream(Byte data, Int32 offset, Int32 size)
System.Web.HttpWriter.WriteBytes(Byte buffer, Int32 index, Int32 count)
System.Web.StaticFileHandler.RespondUsingVirtualFile(String virtualPath, HttpResponse response)
System.Web.DefaultHttpHandler.BeginProcessRequest(HttpContext context, AsyncCallback callback, Object state)
fbs.Handlers.CustomDefaultHandler.BeginProcessRequest(HttpContext context, AsyncCallback callback, Object state)
System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)
This problem occurs even if there is sufficient memory.
- When you access the performance counters of IIS or of ASP.NET from a computer that is running the 32-bit version of Microsoft Operations Manager 2005, you cannot access the performance counters if they run in 64-bit mode.
