Service stops 'functioning' without error. Garbage collection?

[jwarmuth]

I've written a little test app that creates an event log entry every few seconds. Problem is, it works fine except that after it creates 4 log entries it stops creating entries. The service does not stop or error. All it does it stop creating entries.

If I restart the service, it works again and creates 4 entries, then stops. It should create entries indefinitely, so I'm not sure what is happening.

Here's the code, I'm wondering if this has to do with some kind of garbage collection:

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.ServiceProcess;
using System.Threading;

namespace EventService
{
	public class Service1 : System.ServiceProcess.ServiceBase
	{
		/// <summary> 
		/// Required designer variable.
		/// </summary>
		private System.ComponentModel.Container components = null;
		private string strELSource = "EventLogTheft";
		private string strELLogName = "EventLogTestApp";
		private string strELComputerName = ".";
		private int iCounter = 0;
		public Timer tmr5Seconds = null;
		//private Clock myClock;


		public Service1()
		{
			// This call is required by the Windows.Forms Component Designer.
			InitializeComponent();
			try
			{
				//new code
				Clock myClock = new Clock();
				TimerCallback delTimerMethod = new TimerCallback(timedEvent);
				Timer tmr5Secs = new Timer(delTimerMethod, myClock, 0, 5000);
				myClock.tmr = tmr5Seconds;

				if(!EventLog.SourceExists(strELSource, strELComputerName))
				{
					Debugger.Break();
					Console.WriteLine("Source does not exist. I'll try to create");					
					//EventLog.CreateEventSource(strELSource, strELLogName, strELComputerName);
				}					
			}
			catch (Exception ex)
			{
				Console.WriteLine(ex.ToString());
			}
		}

		// The main entry point for the process
		static void Main()
		{
			System.ServiceProcess.ServiceBase[] ServicesToRun;
	
			// More than one user Service may run within the same process. To add
			// another service to this process, change the following line to
			// create a second service object. For example,
			//
			//   ServicesToRun = new System.ServiceProcess.ServiceBase[] {new Service1(), new MySecondUserService()};
			//
			ServicesToRun = new System.ServiceProcess.ServiceBase[] { new Service1() };

			System.ServiceProcess.ServiceBase.Run(ServicesToRun);
		}

		/// <summary> 
		/// Required method for Designer support - do not modify 
		/// the contents of this method with the code editor.
		/// </summary>
		private void InitializeComponent()
		{
			components = new System.ComponentModel.Container();
			this.ServiceName = "Service1";
		}

		/// <summary>
		/// Clean up any resources being used.
		/// </summary>
		protected override void Dispose( bool disposing )
		{
			if( disposing )
			{
				if (components != null) 
				{
					components.Dispose();
				}
			}
			base.Dispose( disposing );
		}

		/// <summary>
		/// Set things in motion so your service can do its work.
		/// </summary>
		protected override void OnStart(string[] args)
		{
		}
 
		/// <summary>
		/// Stop this service.
		/// </summary>
		protected override void OnStop()
		{
		}

		private void timedEvent(Object o)
		{
			try
			{
				Clock myClock = (Clock)o;
				iCounter+=1;
				EventLog el1 = new EventLog();
				el1.Source = strELSource;
				el1.Log = strELLogName;
				el1.WriteEntry("Timed event. Second: " + iCounter.ToString());
				Console.WriteLine(iCounter.ToString());
			}
			catch (Exception ex)
			{
				Console.WriteLine(ex.ToString());
			}
		}
	}
	
	public class Clock
	{
		public Timer tmr;
	}

}

Perhaps a suggestion on how to collect info on the running process?

Some freeware that might help.
