Attempted to read or write protected memory followed by Load Report Failed

99 Views

After running OK for some time ASP.NET web application (VS 2008 .NET 3.5 with Crystal Reports included) running on MS WIN 2003 R2, SP2) will throw error when trying to create PDF crystal report. Error reads as follow:

Attempted to read or write protected memory. This is often an indication that other memory is corrupt. - at CrystalDecisions.ReportAppServer.ClientDoc.ReportClientDocumentClass.Close() at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.InternalClose(Boolean bSetupForNextReport, Boolean bAutoClose) at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.Dispose(Boolean bDisposeManaged) at System.ComponentModel.Component.Dispose() at CrystalDecisions.CrystalReports.Engine.ReportDocument.InternalClose(Boolean bSetupForNextReport) at CrystalDecisions.CrystalReports.Engine.ReportDocument.Close()

After that every consecutive attempt to create another PDF crystal report will fail with fallowing error:

Load report failed. - at ... at System.Web.UI.WebControls.Button.OnClick(EventArgs e) at System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) at System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

Once Application pool is recycled, error goes away but comes back after while. It seems that recently the uptime is getting shorter.

Anyone had similar experience, posible solution?

Thanks in advance,
