IIS wkhtmltox.dll_unload error

[jackiemanzzz]

I got this error both local machine and IIS server when HtmlToPdfDocument's objectSettings include urls for header, footer and also body.
If i used just one htmlUrl for pdf, i didn't get this error. Unfortunately, I have to use a link either footer or header cause i have many dynamic data to put there.

My code like that

var document = new HtmlToPdfDocument
        {
            GlobalSettings = {
                ProduceOutline = true,
                DocumentTitle = title,
                Orientation = orientation,
                PaperSize = PaperKind.A4,
                Margins =
                {
                    Left = 1.375,
                    Right = 1.375,
                    Top = top,
                    Bottom = bottom,
                    Unit = TuesPechkin.Unit.Centimeters

                }
            },
            Objects = {
                new ObjectSettings {
                    PageUrl = link,
                    HeaderSettings = new HeaderSettings{HtmlUrl = headerPath, ContentSpacing = 2 },
                    FooterSettings = new FooterSettings{HtmlUrl = footerPath,}
                }
            }
        };
        var tempFolderDeployment = new TempFolderDeployment();
        var win32EmbeddedDeployment = new Win32EmbeddedDeployment(tempFolderDeployment);
        var remotingToolset = new RemotingToolset<PdfToolset>(win32EmbeddedDeployment);

        var converter = new ThreadSafeConverter(remotingToolset);

        byte[] result = converter.Convert(document);
        remotingToolset.Unload();

Windows event viewer error likes that

Notes:
1)I dont get this error every time.
2)my html url is not local url.
3)if i wait thread 1000 ms before remotingToolset.Unload(), frequency of the error decreases.

Is there anyone to suggest something?

Just use static object for
TempFolderDeployment(); Win32EmbeddedDeployment(tempFolderDeployment);
RemotingToolset(win32EmbeddedDeployment);

Its written in readMe file. I also changed tempFolder to staticFolder
