Crashing with plotsupp.cpp line 4049 internal error

[rodrigue]

Hi all,

I m developing an application with LabView 8.5 Full Dev under WindowsXP.

Since several days, when working on my application, labview crash I(about 10 times a day) with internal error plotsupp.cpp line 4049 (on 3 different computers).

It crash when vi is running, but also when it stopped and when I edit it. It also sometimes crash after having closed all vi s and finally closing the Labview welcome window. In attachement there is 1 crash log. It s difficult because it is not reproducible (there is no action that systematically crash) and lot of different action can induce crashing (e.g opening a sub vi digram, moving a window, clsing a window,...).

Has I presume there could be a link with the display in my front panel, I ll describe them:

Some numerical and bool display in clusters

1 chart with 151 pts in history length

2 pictubre box (about 250x250 pix) with transparent background

That- s it.

I ve found this message which is quite similar with my problem.

FYI, I tested the vi proposed and it doesn t crush on my computer.

Has my application is critical, I can afford it crashing...

I hope you can help me identifying the proble, and fixing it.

It wont be easy for you to test my vi because it use external devices, (1 tcp ip connection, and serial connection) but if needed i can try to remove these inputs).

Looking forward to hear from you

Hey,

Do you have your charts update mode set to strip, scope or sweep? If it is sweep just change to one of the others.

Anyway I would suggest to go on with the other thread because Nick allready reported it to R&D and they will be happy for any additional log file.

Hey Christian,

Thank you for your advie. In fact, I was using sweep as update mode. I changed it to scope and till now, it didn't crash again. A bit too early to conclude that it resolves the problem, but promising. As I realy need a sweep behavirour, I'm considering creating my own sweep chart with a picturebox and mulitline. Do you think it'll take more resources? Is there a place to find such code or buy them.

I'll continue the other thread and add more info soon.

Thanks again

Hi,

I had the same problem.

My simulator program, 10 msec loop, crashed only on Dual core processors.

The same program in single core processor never gave the problem.

Maybe thats why the problem did not show up if tested by NI.

I changed the update mode form swwep to normal and the problem never showed up again.

The crash can happen after seconds as well after hours, but it crashes LV.
