I'm thinking the same thing after reading that post. Because I'm seeing were the data stream or read might not close because it crashed to the try catch. I'll rewrite this and see it that's the issue.

Calling the equivalent in java posses no issues. I'm reminded of https://bugzilla.novell.com/show_bug.cgi?id=648862#c9 However, I see that you are disposing of `response` and other Stream instances, so I'm not sure where the leak is coming from. That said, you have lots of catch{} blocks; are those being hit? I ask because there are code paths where, if an exception were thrown, the stream wouldn't be closed: Stream dataStream = request.GetRequestStream(); // Write the data to the request stream. dataStream.Write(byteArray, 0, byteArray.Length); // Close the Stream object. dataStream.Close(); Instead, try: using (Stream dataStream = request.GetRequestStream()) dataStream.WRite (byteArray, 0, byteArray.Length); I would actually suggest using `using` more often, as I found that method hard to read (but that may be just me), e.g. a simple translation would be: private string GetData(string url, Boolean postData, String xmlData) { StringBuilder sb = new StringBuilder(); try { using (var request = (HttpWebRequest) WebRequest.Create(url)) { request.ContentType = "text/plain"; if (postData) { request.Method = "POST"; byte[] data = Encoding.ASCII.GetBytes(xmlData); request.ContentLength = data.Length; using (o = request.GetRequestStream()) o.Write (data, 0, data.Length); } using (var response = (HttpWebResponse) request.GetReponse()) using (var resStream = response.GetResponseStream ()) { byte[] buf = new byte[4 * 1024]; int count = 0; do { count = resStream.Read (buf, 0, buf.Length); if (count != 0) sb.Append (Encoding.ASCII.GetString(buf, 0, count)); } while (count > 0); } } } catch {} return sb.ToString (); } - Jon _______________________________________________ Monodroid mailing list Monodroid@lists.ximian.com UNSUBSCRIBE INFORMATION: http://lists.ximian.com/mailman/listinfo/monodroid _______________________________________________ Monodroid mailing list Monodroid@lists.ximian.com UNSUBSCRIBE INFORMATION: http://lists.ximian.com/mailman/listinfo/monodroid
