Memory Leak from a loop inside thread.

Question

Hi everybody I am having memory leak problem from inside the thread. I have create this thread which does a monitoring on certain activity. This thread may run for 3/4 days. I have put a While loop inside the thread which is making the thread to do the same monitoring task again and again. This thread also interacts with the database too. Environment : language : C# Databse : SQLite (its a small database and is open source). I have tried different methods to reduce the memory leak problem such as: -Disposing all the class when not in used. -called the GC forcefully. -closing unmanaged resources etc. Please try to help me solve this problem. Thank you shakti

The code which is giving the problem is as follows. private void StartRealTrading() { string CurrencyPair = String.Empty; SimulationData Simulate = new SimulationData(); DataRow[] dRows; string PossessedCurrencyPair = string.Empty; bool IsPossessed = false; DataTable DtPossessed = new DataTable(); int cnt = 0; try { while (true) { if (cnt > 100) { GC.Collect(); cnt = 0; } cnt++; if (!_Start) break; try { // This function check the information from Database if (!GetDBPossessedCurrency(ref PossessedCurrencyPair)) this.AddOrderInformation = true; Thread.Sleep(500); // This Function dequeues object from queue and stores it into datatable if the AddOrderInformation ==true. DequeueOrderInformation(); //check if start date has crossed or not. if (DateTime.Now mUsrSetting.EndDate) break; //check if any currency pair exists for monitoring or not. dRows = dtOrderInfo.Select(DoMonitoring = 1 ); // 1= do monitoring  0 = don't do monitoring if (dRows == null || dRows.Length == 0) { continue; } } catch (ThreadAbortException) { break; } catch (Exception ex) { this.mELog.WriteError(StartRealTrading1 ex false); } //foreach (DataRow dRow in dtOrderInfo.Rows) for(int i=0;i
