Windows Service Application - Process

Hi,

I have developed a windows service application, by using multi threading, multiprocessing too.

Problem 1 : After service starts it takes the server into 100% CPU usage.

Problem 2 : If suppose i stop the service also, the process not stop, i can able to monitor that through task manager and resource monitor too..

Problem 3 : If no communication takes place with the service means also, the thread waiting in "Analysis Wait Chain"

Sample coding:

while ((true && serverEndData != "END"))
{
    try
    {
      requestCount = requestCount + 1;
      NetworkStream networkStream = clientSocket.GetStream();
      networkStream.Read(bytesFrom, 0, 1);

      ss = Encoding.ASCII.GetString(bytesFrom, 0, bytesFrom.Length);
      fullRecDate = fullRecDate + ss.Trim();

      getData[rec] = bytesFrom[0];
      rec = rec + 1;

       if (rec == 48)
       {
          rec = 0;
          fullRecDate = DecryptTheData(getData);
          Log(fullRecDate, "Main", "Smart");
          string Str_DEcryptedData = string.Empty;
      
          for (int lo = 0; lo < 48; lo++)
          {
            byte a3 = getData[lo];
            int ij = Convert.ToInt32(a3);
            Str_DEcryptedData = Str_DEcryptedData + " " + DecimalToBase(ij);
          }

          string smartid = fullRecDate.Substring(0, 3);
          string hhid = fullRecDate.Substring(0, 3);
          string sbsend = fullRecDate.Substring(0, 4);

          if (smartid == "NSP")
          {
            try
            {
              string smartid = fullRecDate.Substring(5, 5);
              Log(fullRecDate, "NSP", smartid);
              string SPinfo2 = "";
              SPinfo2 = "NSP" + DatePacket + SPinfo1;

              SPinfo2 = SPinfo2.PadRight(48, '0');
              Log(SPinfo2, "NSP ACK", Smartid);  // smartid);

              byte[] encryptNsbData = EncryptTheDate(SBinfo2);
              networkStream.Write(encryptNsbData, 0, encryptNsbData.Length);
            }
            catch (Exception err)
            {
              Log(err.Message, "New SP", "SP");
            }
          }
          else
          {
            serverEndData = "END";
            networkStream.Flush();
            networkStream.Close(100);
            Log("END", "Server Closed Connection ", "");
          }
        }
      }
      catch (Exception ex)
      {
        Log(ex.Message, "ReadDataFromDevice[Main Communication]", "Smart");
        break;
      }
    }
  }
  catch
  {
    WriteLog("Application", "Smart", "Main Communication ", "Error");
  }
}

I have verified that while communication starts one thread is opening after the communication ends, it was closing properly, i have monitored by using system log file as well as service log file too. While continuous monitor of 5 hours, not extra threads running and not makes CPU into high usage, while not monitoring for 8 -10 hours gap, while we checking there will be unclosed threads will be maintain in the "Analysis wait Chain".
