C#: Handle count is getting increased

Question

Hi,
I have developed an application in C# that is doing some database operations.
I am calling a method that is doing DB operation inside infinite do while loop and pausing the application for 1 second using Thread.Sleep(1000).
When I left the application running for 2 or more days then I came to know that handle count(Displayed in Task Manager) has increased about 40000 and its growing contineously...
Below is the sample code that I am using in my application:
private static void Process()
                try
                    do
                        if (oCon.State == ConnectionState.Closed || ((int)DateAndTime.DateDiff("n", DateTime.FromOADate(gDtHrConect),
DateTime.Now, FirstDayOfWeek.Sunday, FirstWeekOfYear.Jan1)) >= 20)
                            fReCon();
                        DoSomeDbOperation();
                        Thread.Sleep(1000);
                    while (true);
                catch
Please suggest why handle count is increasing? is this issue related to Threading?
high valume of Handles can create problem in the application?
Please do let me know if you need further details on this.
Thanks for your help.

Hello Pramod,
You could follow the suggestion from Joel, you could firstly comment out the “DoSomeDbOperation()” method to see if it then would work find without increasing the handle count. This would help narrow down this issue.
And with your description, this issue seems to be a handle leak, then you could also check this blog below which would help you find what type handles leak:
