Topshelf Services not stopping gracefully

[Stephen Mc Gowan]

Hey,

I've been having issues with services built with Topshelf. I've
included my code below to show exactly what I'm doing. I'm using
Topshelf 2.1.0.0, services built for .Net v 3.5 and deployed on
Windows Server 2008 R2

I've built a number of services that are all having the same problem
and I've tested the basic TownCrier example below and I see the same
issue. If I leave them running for a while (30 minutes from casual
observation) the services won't stop gracefully. The Trace.Writeline
statements at the end of my stop method are being executed, as I can
see them in my logs, but the service appear to hang after this. The
after a while I get the following error, and the service isn't
stopped.

"Windows could not stop the TownCrier service on Local Computer. The
service did not return and error. This could be an internal Windows
error or an internal service error. If the Problem persists, contact
your system administrator."

If I try to stop the service a second time, I get this error and the
service appears to be killed by the service manager in Windows.

"Windows could not stop the TownCrier service on Local Computer.

Error 1061: The service cannot accept control messages at this time."

I'm deploying the service with "Towncrier.exe install" and then
starting it in the Windows service manager. Any ideas? Is there a way
to turn on debugging information for Topshelf? I've included my code
below, my trace listener is just a TextWriterTraceListener configured
in a app.config file.

namespace testTopShelf
{
using System;
using System.IO;
using System.Timers;
using System.Diagnostics;
using Topshelf;
using Topshelf.Configuration;
using Topshelf.Configuration.Dsl;

internal class Program
{
static void Main(string[] args)
{
RunConfiguration cfg = RunnerConfigurator.New(x =>
{
x.ConfigureService<TownCrier>(s =>
{
s.Named("TownCrier");
s.HowToBuildService(name => new TownCrier());
s.WhenStarted(tc => tc.Start());
s.WhenStopped(tc => tc.Stop());
});
x.RunAsLocalSystem();
x.SetDescription("Towncrier");
x.SetDisplayName("Towncrier");
x.SetServiceName("Towncrier");
});

Runner.Host(cfg, args);
}
}

public class TownCrier
{

readonly Timer _timer;

public TownCrier()
{
Trace.WriteLine("Init");
_timer = new Timer(1000) {AutoReset = true};
_timer.Elapsed += (sender, eventArgs) => onTimer();
}

public void onTimer()
{
string time = DateTime.Now.ToString();
Console.WriteLine(time);
Trace.WriteLine(time);
}

public void Start()
{
Console.WriteLine("Starting");
Trace.WriteLine("Starting Service");
_timer.Start();
Trace.WriteLine("Started");
}

public void Stop()
{
Console.WriteLine("Stopping");
Trace.WriteLine("Stopping Service");
_timer.Stop();
Trace.WriteLine("Stopped");
}
}
}

This has been fixed with the latest release of TS, version 2.2.

[Stephen Mc Gowan]

Cheers,

I had tried with the latest version but I was having issues because
the code examples on the website were out of date. This was leading to
deprecated code warnings at compile time and the services not
installing properly.

Just tried it with the code examples that are in the source on GitHub
and that appears to be working fine.

Is there plans to update the website? The documentation and code
examples appear to be out of date and the "Topshelf Binaries" link off
the documentation page links to version 2.0.

Code sample updated: see http://topshelf-project.com/documentation/getting-started/
Downloads link is also now pointing to the github/downloads instead of a specific one.

[Rob Gibbens]

What is/was the difference? What needed to be changed between 2.0 and
2.2? We're having the same issues.

[Dru Sellers]

Which issue are you having Rob.

-d

[Rob Gibbens]

When I run "MyApp.exe install", the install doesn't work anymore. The
service simply starts in Console Mode.


When I press Ctrl-C, the service outputs...

INFO [ServiceCoordinator] - [Topshelf] After stopping services
complete
INFO [ConsoleRunHost] - [Topshelf] Stopped

But the service just hangs, doesn't stop.

[Rob Gibbens]

And this problem appears to have started when we upgraded from 2.0 to
2.2.

Ok, cool beans. More info is better. :)

What does your config look like?

-d

[Rob Gibbens]

var cfg = RunnerConfigurator.New(x =>
{
x.SetDisplayName("V.H.QueuePoller" + instanceName);
x.SetServiceName("V.H.QueuePoller" + instanceName);
x.SetDescription("Processing Service");

x.ConfigureService<IQueuePoller>(c =>
{
c.WhenStarted(s => s.Start());
c.WhenStopped(s => s.Stop());
c.WhenPaused(s => s.Stop());
c.WhenContinued(s => s.Start());
c.HowToBuildService(builder =>
Windsor.Container.Resolve<IQueuePoller>());
});
});

Runner.Host(cfg, args);

[Rob Gibbens]

Also, we have nine different services/apps using TopShelf, and this
problem is now occurring in all of them after upgrading to 2.2. The
configs are all similar.

[Rob Gibbens]

Ah...I now see that there is a HostFactory. I'll try switching to
that and see if it helps.

[Rob Gibbens]

When using HostFactory, what's the equivalent of HowToBuildService?
ConstructUsing?

[Dru Sellers]

ConstructUsing correct

-d

[Rob Gibbens]

That did it. So other people can follow along, I changed my
configuration from..

var cfg = RunnerConfigurator.New(x =>
{
x.SetDisplayName("V.H.QueuePoller" + instanceName);
x.SetServiceName("V.H.QueuePoller" + instanceName);
x.SetDescription("Processing Service");
x.ConfigureService<IQueuePoller>(c =>
{
c.WhenStarted(s => s.Start());
c.WhenStopped(s => s.Stop());
c.WhenPaused(s => s.Stop());
c.WhenContinued(s => s.Start());
c.HowToBuildService(builder =>
Windsor.Container.Resolve<IQueuePoller>());
});
});
Runner.Host(cfg, args);

To...

var h = HostFactory.New(x =>
{
x.Service<IQueuePoller>(c =>

{
c.WhenStarted(s => s.Start());
c.WhenStopped(s => s.Stop());
c.WhenPaused(s => s.Stop());
c.WhenContinued(s => s.Start());

c.ConstructUsing(builder =>
Windsor.Container.Resolve<IQueuePoller>());
});

x.SetDisplayName("V.H.QueuePoller" + instanceName);
x.SetServiceName("V.H.QueuePoller" + instanceName);
x.SetDescription("Processing Service");

});

h.Run();


and am able to install the service and stop the service again. Thanks
for the help.

Actually, I can install now, but pressing Ctrl-C still leaves the
console app running (doesn't return to command prompt). Is this
expected?

INFO [QueuePoller] - QueuePoller Stopped: 5/2/2011 4:19:10 PM

If the RunnerConfigurator no longer works, can it either be removed
completely, or fixed to be backwards compatible? Silently failing is
rather confusing.

CTRL+C fails with Visual Studio 2010, if I recall correctly. I think
Chris is working on a work around which involved another key combo.

I think RunnerConfigurator is still supported but if it's failing
obviously we messed something. Drop a bug in on github and we can
address it.

-Travis

[Rob Gibbens]

Fails when debugging with VS2010, or fails for anything built with
VS2010? I'm running the console app/exe completely outside of VS/
Debugger.

Can you shoot me steps to reproduce. I just tested it on 7 different services and all were good.

-d

[Robert Gibbens]

For the Ctrl-C issue only?

[Rob Gibbens]

I'll see if I can extract it out from our code at work and send a
sample app.

[Dru Sellers]

that would be awesome. thanks!

[Hakeem Mohammed]

Ctrl + C does stop the service running in VS '10 command prompt. It does take a few seconds though. Our set up is similar to what Rob has posted, configured with the HostFactory. Thanks!

[James Bradt]

I've experienced TS not being graceful on shutdown also.

I have various shelved service hosts running (each handling a variety
of services). Right now, these hosts are running in consoles.
(Later, they will be running as windows services)

If I leave the services running for a while (not sure how long), when
I Ctrl-C to shut down, the exception below occurs.

If I Ctrl-C shutdown shortly (within minutes) after starting the
service host, the exception does not occur.

Any suggestions?

Thanks,
James

Hi James,

What version of TS are you running on.
what does your configuration look like.
What version of .net are you running it on.

-d

[James Bradt]

Sorry - forgot to add the extra info.

Let me know if you need more clarification.

Thanks,
James

=============================

dotnet 4
TS 2.2.1.0 - dl'd binary zip from github yesterday. I did not build
from sourcecode.

--------------------

I am using shelving. When debugging inside of VS2010, I send a
serviceChannel message directly to create an internal shelftype
(instead of using the DirectoryMonitor when deployed). I've seen this
exception in both situations (debug and deployed)

-------------------

I start the Hosting.DirectoryMonitor with

Dim message = New CreateShelfService("Hosting.DirectoryMonitor",
ShelfType.Internal, GetType(FileSystem.DirectoryMonitorBootstrapper))
_serviceChannel.Send(message)

------------------

the run method (bootstrapperHost is of type ServiceHost) is configured
as

HostFactory.Run(Sub(x)

x.BeforeStartingServices(Sub()

Console.WriteLine("[Host Bootstrapper] Preparing to start host
services")

_log.Info("[Host Bootstrapper] Preparing to start host services")
End Sub)

x.AfterStartingServices(Sub()

Console.WriteLine("[Host Bootstrapper] All services have been
started")

_log.Info("[Host Bootstrapper] All services have been started")
End Sub)


x.SetServiceName(bootstrapperHost.HostServiceName)

x.SetDisplayName(bootstrapperHost.HostServiceName)

x.SetDescription(bootstrapperHost.HostServiceDescription)

bootstrapperHost.RunAs(x)
'x.RunAsLocalSystem()

x.EnableDashboard()

x.Service(Of ServiceHost)(Sub(y)

y.SetServiceName(bootstrapperHost.HostServiceName)

y.ConstructUsing(Function(name, coordinator)

bootstrapperHost.SetServiceChannel(coordinator)

Return bootstrapperHost

End Function)

y.WhenStarted(Sub(host__1)

host__1.Start()

End Sub)

y.WhenStopped(Sub(host__1)

host__1.[Stop]()

End Sub)

End Sub)

x.AfterStoppingServices(Sub()

Console.WriteLine("[Host Bootstrapper] All services have been
stopped")

_log.Info("[Host Bootstrapper] All services have been stopped")

End Sub)

End Sub)

-------------------------

when using the directoryMonitor, each shelf is config'd by using a
config file

example:
<ShelfConfiguration Bootstrapper="MyService.ServiceBootstrapper,
MyService" />

[Dru Sellers]

ok. so to be clear. in 'prod' this is running as a shelf. you are not directly sending any messages correct?

-d

[James Bradt]

Sorry for the delay in replying...

The only shelf that is being started via a message is the directory
monitor service.

Thanks,
James

[Dru Sellers]

no problem. Does this issue only occur when your service is running? Or does it happen with the host by itself?

-d

[James Bradt]

The issue occurs whether any additional services are running.

The only base services are the TS directory Monitor and the TS
dashboard.

I started up the host as a console app and let is sit idle for a while
(approx 2 hours). I then pressed Ctrl-C and received the same
exceptions as reported above.

I will try the same with the shelving example to see if I can
reproduce it there.

James

[James Bradt]

Today, I actually had time to let the TS host run.

I started "Topshelf.Host.exe" without any services available for
shelving at approx 9:30 am

I Ctrl-C'd the host at approx 1:30 pm.

An exception occurred and I've included the complete log for the host
below.

Let me know if you have any further questions.

Thanks,
James

Interesting, it seems that WCF is hanging up the connection after a period of time. I guess I'll dig into the WCF configuration and see if this is something configurable or if I just need to reconnect if an exception occurs... Hmmm.
