Question

I have a .Net service that has begun to refuse to start – the system log shows that it ‘was successfully sent a start control’ and then five seconds later the ‘service entered the stop state’. I have the Main() function of my service class wrapped in a try/catch block — but when this situation occurs, no errors appear in my events log from my service.

I would like to know what the problem is. If there is some exception that is not being caught – where would it be caught? Below is the code in which I run the service.

using System; using System.Collections.Generic; using System.Linq; using System.ServiceProcess; using System.Text;  namespace MyServerService {     static class service     {         /// <summary>         /// The main entry point for the application.         /// </summary>         static void Main()         {             try                 { #if DEBUG                      System.Diagnostics.Debugger.Launch();  #endif                      ServiceBase[] ServicesToRun;                     ServicesToRun = new ServiceBase[]                  {                      new MyService()                  };                     ServiceBase.Run(ServicesToRun);             } catch (Exception ex)             {                 System.Diagnostics.EventLog.WriteEntry('MyServerService', 'Main() Error: ' + ex.Message + ex.InnerException, System.Diagnostics.EventLogEntryType.Error);             }         }     } }

In this situation, I was writing the to the Windows Application log — in the production environment, the log was full. I’m unsure of what the debugging technique should be to ‘catch’ this class of a problem – but that was the problem for us.
