It seems weird to have a frozen reported with that main thread callstack. Anyway, one "solution" would be to disable the freeze check in the madExcept settings. Of course you'd lose the freeze check functionality that way...

[ira]

If I recall correctly, after i click "Continue application", my program try to execute its self and there will be alert "..app already running" because I use mutex to prevent multiple instances. The program is still running but losing its functionality (could not create new thread etc). The only solution right now is restart the program.

Disabling the freeze check option only makes me kill my program with Task Manager because the way to close my program is I have to click popup menu on notification area/taskbar which is popup menu won't show its menu because of this bug.

[madshi]

I'm not sure if you think that this is a bug in madExcept and madExcept is causing all these problems? If that's true, simply disabling the freeze check in the madExcept settings should "fix" the problem. However, what you're describing sounds more like a problem in your program to me, which is just properly detected and reported by madExcept. The only thing that confuses me a bit is the callstack.

[ira]

No, I'm sure this is a bug from my program.

which is just properly detected and reported by madExcept. The only thing that confuses me a bit is the callstack

That's why I asked about this It seems my problem is same with problem at viewtopic.php?=&p=11387

In that link you said "So my suggestion is to add logging to all your initialization parts to find out where it's stuck."

Did u mean "initialization parts" is like:

Code: Select all

unit UnitName:
....
initialization
 {initialization code goes here}
finalization
 {finalization code goes here}
end.

Thanks in advance.

[madshi]

Well, that thread you're linking to has a callback which makes sense, though. The callstack there clearly indicates that the process is stuck in one of the initialization sections. Your callstack doesn't look like that, so I'm not sure what to suggest. Also you say the problem occurs "sometimes". How often is "sometimes"? And does the occur during the start of your process? Or during the closing? Or in the middle of the runtime?

[ira]

The problem often occurs after program ran in a few hours, so the occur is in the middle of the runtime. My program works in background and it stays on tray icon. It use timer, IPC, MCHook. I don't really understand about frozen app, the only thing that I know frozen can happen if a program/thread being not responding or race condition in timer.

Here's another frozen report from my other program (I've remove some part of report). This report show that ActiveX.CoCreateInstance cause the problem, right? Actually most of my customers send me frozen reports that occurred in initialization but I am lucky because this report show frozen report in a function. I don't know, maybe this report can be a reference for suggesting me .

[madshi]

If madExcept says that your program is "frozen", that practically means that your main thread has not been reacting to messages for a long time.

If your customers send your frozen reports in initialization, then the callstack of their reports may be helpful. For that specific problem the suggestions from the other thread you linked might help you, too. But it's all so much more difficult if you can't reliably reproduce the initialization freeze on your development PC.

Code: Select all

exception message : The application seems to be frozen.

What does TMainForm.GetXXX in line 713 do? Does it create some OLE/COM object?

[ira]

TMainForm.GetXXX contain function that create some OLE/COM/ShellWindows object. This function is called by timer in uQuery 661 +23 TForm2.TimerQuery.

If the code in timer is stack, it can produces frozen because timer run in main thread?

Here is another example frozen in initialization from my past project, the report always like this:

[madshi]

The callstack of your first and last bug report do not indicate that the freezing was during initialization.

Yes, if a timer event freezes during COM/OLE creation then the main thread is "frozen", because the main thread does not handle messages, anymore.

I'd suggest that you create a secondary thread which does those OLE/COM/ShellWindows stuff. Instead of using a timer, you can just use an endless loop and "Sleep(someMilliseconds)". This way if the OLE/COM creation freezes, your main thread will still live on. Maybe you can even add a Timer event to the main thread which just checks whether the OLE/COM secondary thread is still alive and if not, maybe gracefully restart the process or something like that.

The callstack of your first and last bug report do not indicate that the freezing was during initialization.

For my last bug report, so in which part the freezing was occur? I think this is my last question for this thread.

Okay madshi, I will follow your suggestion to create a secondary thread. Thanks a lot.

[madshi]

The callstack indicates that the freeze happened in the middle of the application lifetime, after initialization was complete.

[ira]

The callstack indicates that the freeze happened in the middle of the application lifetime, after initialization was complete.

How to "read" the callstack ? I mean how do you know that "The callstack indicates that the freeze happened in the middle of the application lifetime". I don't want to ask you again and again about reading bug report so please explain it shortly to me . Sorry Madshi, I have not read your MadExcept documentation about callstack (perhaps I will read tomorrow).

btw, I create a secondary thread which does those OLE/COM/ShellWindows stuff. Problem still occurs. It means the problem does not relate with those stuff right?

how do you know that "The callstack indicates that the freeze happened in the middle of the application lifetime".

There's "Application.Run" in the callstack. Basically that means that all unit initialization sections were already full executed, because Application.Run is in the "being ... end" block of the dpr file which is only executed after all unit initialization blocks are done.

btw, I create a secondary thread which does those OLE/COM/ShellWindows stuff. Problem still occurs. It means the problem does not relate with those stuff right?

No. The secondary thread should help avoiding this problem:

Code: Select all

callstack crc     : $f9c9340f, $4c46054e, $079dcb95
exception number  : 1
exception message : The application seems to be frozen.

But it will not help with this one:

exception message : The application seems to be frozen.

These are 2 different problems.
