Help w/ crash, Dr. Watson dump

[Gripster]

Attached is a Dr. Watson dump of a crash that we occassional get on a LV 8.5 created .exe.  We run this .exe on a Window XP machine 24/7 and sporadically see this error about 3-5 times a week.  99% of the time it runs w/o problems.  The program communicates over a serial port VISA to an instrument we manufacture and writes a small log file every minute.

In particular, what is the "*** ERROR: Symbol file could not be found.  Defaulted to export symbols for C:\Program Files\National Instruments\Shared\LabVIEW Run-Time\8.5\lvrt.dll - function: lvrt!JPEGToLVImagePreflight"  trying to do that it can't do?

Anybody taking a look at this one yet?  What does "lvrt!JPEGToLVImagePreflight" do?

[Gripster]

Still need some help on this one...

Hi Bill,

Does it only crash as an executable? or Does it also crash when you run your code as a VI? Is it possible for you to provide us a simple VI that can consistanty reproduce the crash for further investigation purposes?

The target system does not have LV development installed on it.  The target PC we run has embedded RS-485 h/w that will not allow the s/w to run on a normal PC.  However, I test development the program on a standard PC using a RS-232 to RS-485 converter connected to our instrumentation system and I've never seen these errors while developing.  So unfortunately there is no easy way to try the program without significant changes to it and the system itself.  The best thing I can do is upload the project to you on a private site - if I get management & legal approval as the code is highly proprietary.

1) Do your LV low-level development programmers know what the "lvrt!JPEGToLVImagePreflight" does?

2) Also I'm beta testing LV8.6.  Should I try it to see if the error stops?

Hi Bill,

Unfortunately, I cannot find any information regarding to lvrt!JPEGToLVImagePreflight. I cannot discuss about any future releases of LabVIEW. If you have any questions on future releases of LabVIEW. Please call in for support.

Hello Gripster:

I was wondering if you were able to resolve the problem.

I see frequent crashes with my TS script which has 200 plus VI calls. I have LV8.5 and TestStand 4.0 development system.

Did LV 8.6 update help?

I would appreciate your comments.

Thanks.

Hi Mim,

Do you mind posting an error log of what you are seeing?  This can help us find what could be causing the error.

Hi Mim,

I have been doing some research to this crash and all of these cases have been reported in LV 8.5.  Do you have LV 8.6 available to you?  If so, I would try running your tests in 8.6 and seeing if that helps.  Additionally, if there are any drivers you are using, upgrading those drivers to the latest version would help prevent the error.  If you do not have 8.5, I will be getting a little more knowledge on the error to see what we can do to fix this.  Please let me know if you have any questions.
