GDI+ System.Drawing.Bitmap gives error Parameter is not valid intermittently

Question

I have some C# code in an ASP.Net application that does this:

Bitmap bmp = new Bitmap(1184, 1900);

And occasionally it throws an exception \"Parameter is not val

Classes within the System.Drawing namespace are not supported for use within a Windows or ASP.NET service

For a supported alternative, see Windows Imaging Components (msdn), a native library which ironically System.Drawing is based on.
