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
