Hi there,

I'm now blocked by this problem the entire day, read thousands of google results, but nothing seems to reflect my problem or even come near to it... i hope any of you has a push into the right direction for me.

I wrote a client-server-application (so more like 2 applications) - the client collects data about his system, as well as a screenshot, serializes all this into a XML stream (the picture as a byte[]-array]) and sends this to the server in regular intervals. The server receives the stream (via tcp), deserializes the xml to an information-object and shows the information on a windows form. This process is running stable for about 20-25 minutes at a submission interval of 3 seconds. When observing the memory usage there's nothing significant to see, also kinda stable. But after these 20-25 mins the server throws a StackOverflowException at the point where it deserializes the tcp-stream, especially when setting the Image property from the byte[]-array.

I thoroughly searched for recursive or endless loops, and regarding the fact that it occurs after thousands of sucessfull intervals, i could hardly imagine that.

    public byte[] ImageBase
    {
        get
        {
            MemoryStream ms = new MemoryStream();
            _screen.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
            return ms.GetBuffer();
        }
        set
        {
            if (_screen != null) _screen.Dispose(); //preventing well-known image memory leak
            MemoryStream ms = new MemoryStream(value);
            try
            {
                _screen = Image.FromStream(ms); //<< EXCEPTION THROWING HERE
            }
            catch (StackOverflowException ex) //thx to new CLR management this wont work anymore -.-
            {
                Console.WriteLine(ex.Message + Environment.NewLine + ex.StackTrace);
            }
            ms.Dispose();
            ms = null;
        }
    }

I hope that more code would be unnecessary, or it could get very complex...

Please help, i have no clue at all anymore

thx Chris
