Is anyone else getting this problem with a basic AsyncUpload upload, we have started to get this exception a lot since a windows update was installed:
It does not seem to be telerik version specific as this is affecting websites using the old DLL too.
The call stack is as follows:
System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.IO.IOException: The process cannot access the file because it is being used by another process.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.File.InternalMove(String sourceFileName, String destFileName, Boolean checkHost) at popup_AddBulkFiles.RadButtonSaveFile_Click(Object sender, EventArgs e) at Telerik.Web.UI.RadButton.OnClick(ButtonClickEventArgs e) at Telerik.Web.UI.RadButton.RaisePostBackEvent(String eventArgument) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.HandleError(Exception e) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest() at System.Web.UI.Page.ProcessRequest(HttpContext context) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)
Also more seriously it seems to be corrupting files uploaded too e.g. a chunk of a file which was at the beginning is being duplicated in the middle.
I would report this as a bug but I have not been able to replicate it from my end.
