需要帮助或至少检查我做错了什么。

我有一个Windows服务，该服务每天按计划运行，它需要一个内部ID和相关URL的列表，然后将该列表分成若干批（我使用的是带有2个元素的批处理），代码循环遍历所有批处理，并发出Web请求，并将当前批处理中每个ID的结果写入数据库（日志）。每个请求都有自己的线程和预定义/静态超时。

我遇到两个问题：

第一个日志被写入，但是第一次运行时，它会与它在列表中找到的第一个ID（底部的示例）相同。

第二个，这个，我不知道这是“我的”问题，还是网站，它始终是相同的URL，只是不同的QS参数。我对每个请求都有一个静态超时，在示例3秒内，在第二个请求之后，我总是超时。

List<List<keyvaluepair<long,string>>> batchList = new List<List<keyvaluepair<long,string>>>(10);

//Get Credentials and timeout value one time
ICredentials credentials = getcredentials(); //Get default credentials,doesnt change
int clickTimeout = 3; //will be seconds
int j = 1;

//Loop
foreach (List<keyvaluepair<long,string>> batch in batchList)
{
    LogHelper.InsertJobLog("ServiceName",string.Format("Executing batch: {0}.",(j).ToString()),reference);
    HandleProcessBatch(batch,credentials,clickTimeout);
    LogHelper.InsertJobLog("ServiceName",string.Format("End Executing batch: {0}.",reference);
    j++;
}

// ....

//Handle batches of processes
private static void HandleProcessBatch(List<keyvaluepair<long,string>> procList,ICredentials credentials,int clickTimeout)
{
    try
    {
        //Task list
        List<Task> listaTarefas = new List<Task>();
        foreach (keyvaluepair<long,string> proc in procList)
        {
            LogHelper.InsertJobLog("ServiceName",string.Format("ProcID {0} will be added to the execution list: {1}",proc.Key,proc.Value),null);
            listaTarefas.Add(
                Task.Factory.StartNew(
                    () => SimulateURLRequest(proc.Key,proc.Value,clickTimeout)
                    )
                );
        }

        //Wait for all tasks in this list to end
        Task.WaitAll(listaTarefas.ToArray());
    }
    catch (Exception ex)
    {
        EventLogWrite.Error("ServiceName-HandleProcessBatch",ex.Message);
    }

}

//Called in diferrent threads
private static void SimulateURLRequest(long processID,string processURL,int timeout)
{
    try
    {
        Uri ipacURL;
        if (!Uri.TryCreate(processURL,UriKind.Absolute,out ipacURL) || (ipacURL.Scheme != Uri.UriSchemeHttp && ipacURL.Scheme != Uri.UriSchemeHttps))
        {
            LogHelper.InsertJobLog("ServiceName",string.Format("Proc {0} URL not valid: {1}",processID.ToString(),processURL),null);
            return;
        }
        WebRequest wr = WebRequest.Create(ipacURL); 
        wr.Credentials = credentials;
        wr.Timeout = (timeout * 1000);
        Httpwebresponse answer = (Httpwebresponse)wr.GetResponse();

        LogHelper.InsertJobLog("ServiceName",string.Format("Proc {0} result: {1}",Enum.GetName(typeof(HttpStatusCode),answer.StatusCode)),null);
    }
    catch (WebException wex)
    {
        LogHelper.InsertJobLog("ServiceName",wex.Message,null);           
    }
    catch (Exception ex)
    {
        LogHelper.InsertJobLog("ServiceName",ex.Message,null);
        EventLogWrite.Error("ServiceName-SimulateURLRequest",ex.Message);
    }
}

ID 20973792被两次写入数据库，此后它开始产生超时...

我看不到我在做什么...
