Fatal Internal Error: "ThEvent.cpp", line 190

HiI have a project in Labview 8.5. The project is made of: Statechart module and vision. The project contains few hundreds of vi.When I am running the project I receive the flowing error: Fatal Internal Error: "ThEvent.cpp", line 190. When I try to investigate the problem using probes and break points, the problem doesn't appear. When the error appears Labview doesn't record any debug information.

Do you mean that the next time you launch LV you don't get the dialog to investigate the error? After LV has crashed (after you have clicked ok on the fatal internal error dialog and LV has exited), can you look in your %temp% directory for something named like "LabVIEW_8.5..._log.txt"? If you can find that, it would help the investigation start.

Also, does it reliably crash after a certain period of time, when you do something, etc?

On the next launch of LV, after the crash, I don't get the dialog box to investigate the problem.I look for  "LabVIEW_8.5..._log.txt", file with name like this doesn't exist on the hard disc.The crash happens after the hardware initialization and right after entering into statechart.Regards, Gabi

It is very peculiar that the log file is not being written.

However, that particular internal error is triggered by some code that detects things like memory corruption, so perhaps LV is so unstable before the crash that it can't even get the log file output to disk.

If you have files we can reproduce this with, it would be very helpful. If the setup is not simple (I noticed you mentioned hardware initialization) or if you would prefer to not post things here, let me know and we can get someone to communicate with you over email to try to get more info to reproduce/diagnose the issue.

Thanks,

I've got the same error message: this error happens after launching several Vi dynamicaly that are shown in a secondary front-panel. The hardware is simulated. The error file says:

I don't understand anything. The VI work properly a few days before and since, I haven't made big modifications.

Hi

I found the problem in camera driver that I am using. I change the way I am working with the camera and this overcome the problem.

Thank you, I will look at the hardware.
