Hi all,

I'm using the lastest version of the library with the next code:


using (ZipFile comprimido = new ZipFile())
                    comprimido.Comment = "Compresion generada por el servicio " + fechaActual.ToString("yyyy-MM-dd HH:mm");
                    comprimido.MaxOutputSegmentSize = 1024 * 1024 * 50;
                    if (!registro.SobreEscribir && System.IO.File.Exists(archivo))


where "registro" is a datarow from typed data source, "archivo" is a filename of the zip file, and "fechaActual" is an instance from DateTime.Now, when i use this code with directories with a lot of sub folders and files (small, midle and big sized files), it runs until the process stop(or get into wait state). i tried to verify the problem in the souce code of Ionic.Zip dll, and  when the zip process get blocked (always get blocked in the same file), i press pause in my depurator and the current line that shows me is _newlyCompressedBlob.WaitOne(); at Line 930, at file ParallelDeflateOutputStream.cs, it doesn´t happen when I use step by step debbugging, in this case the process finish the zip file without errors.

When i tried solve the problem, i deleted the file where the processes stuck, but the process get blocked in another file,


Anybody has any idea of my problem

It sounds to me that it is failing in the parallel compression. You can use ParallelDeflateThreshold = -1, to disable parallel deflation, to avoid th eproblem.  In the meantime it sounds like a bug in the compressor, which I will need to fix.
