.NET Windows Service with timer stops responding
- by Biri
I have a windows service written in c#. It has a timer inside, which fires some functions on a regular basis. So the skeleton of my service:
public partial class ArchiveService : ServiceBase
{
Timer tickTack;
int interval = 10;
...
protected override void OnStart(string[] args)
{
tickTack = new Timer(1000 * interval);
tickTack.Elapsed += new ElapsedEventHandler(tickTack_Elapsed);
tickTack.Start();
}
protected override void OnStop()
{
tickTack.Stop();
}
private void tickTack_Elapsed(object sender, ElapsedEventArgs e)
{
...
}
}
It works for some time (like 10-15 days) then it stops. I mean the service shows as running, but it does not do anything. I make some logging and the problem can be the timer, because after the interval it does not call the tickTack_Elapsed function.
I was thinking about rewrite it without a timer, using an endless loop, which stops the processing for the amount of time I set up. This is also not an elegant solution and I think it can have some side effects regarding memory.
The Timer is used from the System.Timers namespace, the environment is Windows 2003. I used this approach in two different services on different servers, but both is producing this behavior (this is why I thought that it is somehow connected to my code or the framework itself).
Does somebody experienced this behavior? What can be wrong?
Edit:
I edited both services. One got a nice try-catch everywhere and more logging. The second got a timer-recreation on a regular basis. None of them stopped since them, so if this situation remains for another week, I will close this question. Thank you for everyone so far.
Edit:
I close this question because nothing happened. I mean I made some changes, but those changes are not really relevant in this matter and both services are running without any problem since then. Please mark it as "Closed for not relevant anymore".
