I've got an app that does a number of externally focused things: twitter via oAuth, connecting to my web server services, etc. And everything works great, but after about 3-4 minutes of heavy use, the app starts throwing:
Error: ConnectFailure (System call failed)
More specifically:
at System.Net.HttpWebRequest.EndGetRequestStream (IAsyncResult
asyncResult) [0x00000] in <filename unknown>:0
at System.Net.HttpWebRequest.GetRequestStream () [0x00000] in <filename
unknown>:0
at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke
(System.String method_name, System.Object[] parameters) [0x00000] in
<filename unknown>:0
Now, I can trap for this. But the bigger issue is, once I get this error,
the app NEVER recovers. It won't connect to my RSS feeds, Twitter oAuth, or
any of my webservices. I continue to get the same connectfailure error until
I restart the app.
Could this be a case of me not disposing manually of some resource that I
should be? Here's some code from my webservice data pull, but keep in mind,
this is only one of many ways I connect.
List<BBStandings> rank = new List<BBStandings>();
try{
var service = new ServiceName.Service();
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(service.GetStandings());
string s = xmlDoc.InnerXml;
-- bunch of variables declared
int iCount = 1;
if (s != "<NewDataSet />")
{
System.Xml.XmlTextReader xml = new
System.Xml.XmlTextReader(new
System.IO.StringReader(s));
int iXML = 0;
while (xml.Read())
{
switch (xml.NodeType)
{
case XmlNodeType.EndElement:
iCount = 1;
sElement = "";
sText = "";
break;
case XmlNodeType.Element:
sElement = xml.Name;
iCount = 2;
break;
case XmlNodeType.Text:
//sElement = xml.Name;
sText = xml.Value;
iCount = 3;
break;
}
if (iCount == 3)
{
switch (sElement)
{
case "TeamID":
sTeamID = sText;
iCount = 1;
break;
case "TeamName":
sTeamName = sText;
iCount = 1;
break;
case "ConferenceRecord":
sConferenceRecord = sText;
iCount = 1;
break;
case "Record":
sRecord = sText;
BBStandings r = new
BBStandings();
r.TeamID =
Convert.ToInt32(sTeamID);
r.TeamName = sTeamName;
r.ConferenceRecord =
sConferenceRecord;
r.Record = sRecord;
rank.Insert(iXML, r);
iXML += 1;
sTeamID = "";
sConferenceRecord = "";
sTeamName = "";
sRecord = "";
sText = "";
sElement = "";
break;
}
}
}
}
}
catch (Exception ex)
{
string s=ex.Message;
}
return rank;
