Sorry wrong group.

We have an application that can be used as an application server for
WinForms apps (using .NetRemoting) and can be used as WebServices server.
Everything is fine when server is low loaded.
But when we do a stress loading tests (many users, many requests) DW.NET
breakes down.
When our app server consumes ~1.5Gb memory we are always getting one of
the two errors:


First:
Attempted to read or write protected memory. This is often an indication
that other memory is corrupt.

at DataWindowInterop.DW_Events.CatchNotify(Int32 given_HWND, UInt32
Message, UInt32 wParam, Int32 lParam, Void* VM_Object)

at DataWindowInterop.SemanticFunctions.Retrieve(IntPtr given_DW, Boolean
repaint, Object[] ArgsList)

at Sybase.DataWindow.Shared.Retrieve(IntPtr pDW, Boolean bRepaint,
Object[] ArgsList)

at Sybase.DataWindow.DataStore.Retrieve(Object[] ArgsList)



Second:
System.AccessViolationException: Attempted to read or write protected
memory. This is often an indication that other memory is corrupt.

at DataWindowInterop.Services.LoadDWFromLibraries(String[] Libraries,
String DWName, Int32 AdditionalParam)

at Sybase.DataWindow.Shared.NarrowDownDataWindowObject(String
LibraryList, String DWName, Boolean& DidLoading, Boolean& ObjectIsPsr,
String& PsrFile)

at Sybase.DataWindow.DataStore.RecreateDataStore()

at Sybase.DataWindow.DataStore..ctor(String InitLibraryList, String
InitDataWindowObject)



We are using DW.NET_2.0_5048

Unfortunaly i can`t reproduce this with some synthetic tests.
