I get this error during ui automation and am unable to resolve it.
This stops my automation flow ...
instruments[34247:1345307] Attempting to set event horizon when core
is not engaged, request ignored
In my experience, this message is related to the startup or shutdown of the individual processes that enable UIAutomation; nothing in your javascript code or environment really has an effect on it. It's just a sporadic error that comes from somewhere in Apple's software.
Sometimes it happens at the beginning of the run (in which case your javascript code will never be executed), or at the end of the run (in which case your code has already run). If you are seeing this error at the end of a test run and your code did not fully execute, then the real error is probably happening sometime before this -- you are just seeing Apple's error as well on the test shutdown.
The Delphi app tethering manager reserves 20 ports in the range from 2020-2039 to start up its communication threads.
I wanted to find out what happens, when the 21st application is started on the same computer. It turns out that this application just hangs unresponsive until it is killed and I haven't found a way to terminate it gracefully.
To reproduce, just drop a TTetheringManager and a TTetheringProfile on an empty form, connect the profile to the Manager, compile, start the application 20 times outside the IDE and finally start the 21st instance in the IDE.
This is what I have found out so far:
In System.Tether.NetworkAdapter: procedure TTetheringNetworkManagerCommunicationThread.Execute;
an ETetheringException.Create(SManagerNetworkCreation) is raised when either the TCP or the UDP communication server could not be started. So far so good.
This exception shows up in the Debugger. When I continue and step through the following code, the application finally hangs in System: function AcquireExceptionObject and never returns.
Since the application is raised during Application.Run, I tried to catch the Exception via:
try
Application.Run;
except
ShowMessage('Something went terribly wrong!');
end;
but this didn't work. Any suggestions how I can catch (or prevent) this exception?
Since this really seems to be a bug, I filed a quality report for it: https://quality.embarcadero.com/browse/RSP-11345
Can someone explain me when Windows shows this message?
What do i have to do to stop my Program from throwing this exception?
I have a Delphi Windows Forms Program which throws this message short after doing some SQL operations.
So i do the SQL, everything seems fine at first, but at a random time after that windows is killing it by showing this message...
the intresting thing is, it only occours while debugging.
When i'm not debugging it's running perfectly stable.
EDIT: Using RAD-Studio2009
I dont want to turn off the message completely(Only hint i found by using Google)
i want to stop my program giving windows a Reason to do that.
Windows shows this message when an unhandled exception leaks out of your application. This is a fatal condition. Something very wrong has happened with your application because exceptions should all be caught.
You need to work out what is throwing the exception and why it is not being caught. The very first step is to expand the details of the error dialog and find out which module the fault is occurring in, what the fault is and so on. That should yield some high level clues at the very least.
Most likely the Delphi debugger will not be able to help you for such a fault. You need to configure your system to arrange for a crash dump to be produced by the Windows Error Reporting service. Then you can load up the error report in a tool like WinDbg and try to figure it out.
The program starts correctly if I double-click it or if I debug it from VS2010, but it doesn't respond when I try running it from Services.msc. It used to work just fine, but I tried to un-register and then re-register the service to fix a different bug and now I get the following error:
Could not start the PFAdapterMng service on Local Computer.
Error 1053: The service did not respond to the start or control request in a timely fashion.
I tried putting logs at the beginning of main(), and I found out that the service stops responding before it even gets there.
I've tried using Procmon to figure out if there's some registry key missing, but I couldn't find any problems through Procmon.
I've also tried re-registering the service to try to fix it, since re-registering the service was what caused the error in the first place. It doesn't seem to fix anything either.
I've stepped through the program with the parameters -UnregServer and -Service to ensure that the program was being unregistered and registered successfully, and it looks like it's being registered as a service correctly.
Is this because of some error in the registry? I don't see how or why my program stops responding before it even gets to main().
What else could I try to do to debug this problem?
UPDATE:
So, I tried un-registering the service after trying to run it, and it seemed to work fine. I look in services.msc, and I still see that the application is a service. In the past, before I got error 1053, it would just disappear after the first time. I tried un-registering it again, and I got a message box:
Service could not be deleted
So I decided to run the application with the parameter -UnregServer inside of Visual Studio 2010 to figure out what the error is. The function DeleteService() is failing with the error:
ERROR_SERVICE_MARKED_FOR_DELETE
The service is not removed until all open handles to the service have been closed. I stepped through the calls to the CloseServiceHandle() function and it seems like the handles were closed successfully. The service is also not removed if the service is running. I checked Process Manager, and the service was not running. Is the service not being removed because the service stopped responding earlier?
I tried restarting my computer and it was gone. Still, I don't understand why I have to restart my computer when the service used to un-register without the need of a restart before I was getting error 1053. Unless of course I can't un-register the service because the service was not stopped because it stopped responding.
I'll keep trying some more things, but I'm running out of ideas.
UPDATE2:
I tried rebuilding the original application, which I know worked as a service. This means the problem is not related to any of my code. Something is messed up with the Services Control Manager. I don't understand why I only get this error with this application. I have another application which communicates with this application which also needs to be registered as a service. I have no problems with that application. It works perfectly.
But for some reason, this application just stopped responding all of a sudden. I don't know what I changed or broke to cause the service to hang before it even gets to my main() function. The only thing I can think of now to fix the problem is to reformat the server, which is not an option.

I feel stupid.
I've been using Remote Desktop Connection to connect to this server. Well, the service is starting and erroring out. The reason I didn't see any errors or message boxes was because they were appearing on the console session. I was not connected to the console session. I connected to the server using:
mstsc.exe /admin
And now I can see where the program stops responding.
Feels great to waste 10 hours though.
I have a windows service that is failing to start, giving an error "Error 1053: The service did not respond to the start or control request in a timely fashion".
Running the service in my debugger works fine, and if I double click on the the service .exe on the remote machine a console window pops up and continues to run without problem - I can even see log messages showing me that the program is processing everything the way it should be.
The service had been running fine previously, though this is my first time, personally, trying to deploy it with the most recent changes made to the program. I've evaluated those changes and cant figure out how they might cause this problem, particuarly since everything runs fine when not started as a service.
The StartRoutine() method of the service impelmentation is empty, so should be returning in a "timely fashion".
I've checked the event logs on the computer, and it doesn't give any additional information other than it didn't hear back from the service in the 30 second requisite time frame.
Since it works on my machine, and as a double-clicked executable, how would I go about figuring out why it fails as a service?
Oh, and it's .NET 2.0, so it shouldn't be affected by the 1.1 framework bug that exhibited this symptom (http://support.microsoft.com/kb/839174)
The box is a windows server 2003 R2 machine running SP2.
This is a misleading error. It's probably an unhandled exception.
Empty your OnStart() handler then try this in your constructor...
public MainService()
{
InitializeComponent();
try
{
// All your initialization code goes here.
// For instance, my exception was caused by the lack of registry permissions
;
}
catch (Exception ex)
{
EventLog.WriteEntry("Application", ex.ToString(), EventLogEntryType.Error);
}
}
Now check the EventLog on your system for your Application Error.
Could be a number of things and it might help to get a stack trace on the machine exhibiting the problem. There are a number of ways to do this but the point is that you have to see where this is failing in the code.
You can do this with remote debugging, but a simple thing might be to just log to the event logger, or file log if you have that. Literally, putting "WriteLine("At class::function()") throughout portions of the code to see if you've made it there.
This will at least get you looking in the right direction (which ultimately is the code).
Update:
See Microsoft's How to Debug Windows Services article for details in troubleshooting startup problems using WinDbg.
This related question details nice ways to debug services that are written in .NET.
I agree with Scott, the easiest way to find out what's happening is to put some traces in the start-up code (maybe it doesn't even come to your start-up code).
If this doesn't help, you can post your code here so others can take a look.
perhaps lacking some dependence, try this :
- deregister your service
- register again
If fail at register means that lack an module.
If the StartRoutine is empty, you are probably starting it somewhere else.
IIRC you need to fire off a worker thread, and then return from StartRoutine.
One of the problems which may lead to this error is if windows service which needs to be deployed consists of some error i.e it may be simple authorization error or anything as in my case I have referenced some folders and files for logging which were not existing, but when provided the right path of those file and folders it solved my problem.
I ran through every post on this particular subject and none of the responses solved the problem, so I'm adding this response in case this helps someone else. Admittedly this only applies to a new service, not this specific case.
I was writing a File listening service. As a console app, it worked perfectly. When I ran it as a service, I got the same error as above. What I didn't know (and many of the MSDN articles about services conveniently leave out) is that you need to have your class executed from within ServiceBase.Run( YourClassName());. Otherwise, your app executes and immediately terminates and because it terminated, you get the error above even if no error or exception occurred. Here is a link to an article about this. It actually discusses setting up your app for dual use - Console app and service: Create a combo command line / Windows service app
I had that issue and the source of my problem was config file. I edited it in notepad and notepad added one special character which cause service not to run properly because config file was ruined. I saw that special character in notepadd++ and after delete it, service started to run successfully as previous did.
In my case, the correct .NET framework was not installed on the server that I was installing the Windows service on.
One other reason is If you copy the DLL in 'debug' mode to installation folder this issue will come.What you need to do is Run the project in 'Release' mode copy the DLL or directly form Release folder rather than Debug folder,,and copy that DLL in to installation folder,it will work.You can see the reduction in size of DLL ,it will not contain any debug symbols and like that
