已建立的連接被主機中的軟件中止

對不起，如果這是有點長囉嗦，但我認爲更好地張貼更多的更少。已建立的連接被主機中的軟件中止

這也是我的第一篇文章，請原諒。

我一直在試圖找出一段時間。並無濟於事，希望有一位曾經遇到過這樣的天才。

這是一個間歇性問題，很難重現。，我只需運行該代碼調用Web服務 Web服務調用是一個循環（所以我們可以這樣做了很多，1500次以上）

下面是導致該錯誤的代碼：

HttpWebRequest groupRequest = null; 
WebResponse groupResponse = null;    
try 
{  
    XmlDocument doc = new XmlDocument(); 
    groupRequest = (HttpWebRequest)HttpWebRequest.Create(String.Format(Server.HtmlDecode(Util.GetConfigValue("ImpersonatedSearch.GroupLookupUrl")),userIntranetID)); 
    groupRequest.Proxy = null; 
    groupRequest.KeepAlive = false; 
    groupResponse = groupRequest.GetResponse(); 
    doc.Load(groupResponse.GetResponseStream()); 
    foreach (XmlElement nameElement in doc.GetElementsByTagName(XML_GROUP_NAME)) 
    { 
     foreach (string domain in _groupDomains) 
     { 
      try 
      { 
       string group = new System.Security.Principal.NTAccount(domain, nameElement.InnerText).Translate(typeof(System.Security.Principal.SecurityIdentifier)).Value; 
       impersonationChain.Append(";").Append(group);        
       break; 
      } 
      catch{}       
     } // loop through    
    } 
} 
catch (Exception groupLookupException) 
{ 
    throw new ApplicationException(String.Format(@"Impersonated Search ERROR: Could not find groups for user<{0}\{1}>", userNTDomain, userIntranetID), groupLookupException); 
} 
finally 
{ 
    if (groupResponse != null) 
    { 
     groupResponse.Close(); 
    } 
}

這裏有時出現這種情況的錯誤：

Could not find groups for user<DOMAIN\auser> ---> System.IO.IOException: Unable to read 
data from the transport connection: An established connection was aborted by the 
software in your host machine. ---> System.Net.Sockets.SocketException: An established 
connection was aborted by the software in your host machine at

Object[] parameters) at MyProgram. MyWebServices.ImpersonatedSearch.PerformQuery

對不起，這是很多的代碼來通讀。
這種情況約有1700次發生約30次

這個錯誤是客戶端還是服務器端？ – Zote 2009-10-22 16:34:46

客戶端，但這是從web服務拋出 – TheCodeFool 2009-10-22 16:35:46

您可能正在超時。首先，重新啓用Keepalive。其次，檢查請求和回覆的時間戳。如果發送者和接收者之間有防火牆，請確保它沒有因爲空閒超時而關閉連接。過去我遇到過這兩個問題，儘管使用通用套接字編程，而不是數據庫。

將不會感謝您的輸入，我確實保持活着設置爲默認值爲true，但閱讀關於關閉它的帖子，我會嘗試查看超時防火牆謝謝 – TheCodeFool 2009-10-22 16:45:22
