-17502;System Level Exception - TestStand 3.0 Error

When CVI adapter is configured for "in-process" mode (CVI not required), and attached TestStand sequence is ran, there is intermittent error -17502. CVI application error handler does not trap this error - it happens on the sequence level. However, this error cannot be seen when adapter is configured for "Execute Steps in an External Instance of CVI" option.
An input on this issue from the knowledgeable TestStand application engineer is appreciated.

Jelena -
One possibility is that something might be corrupting memory and when running the CVI steps externally, the corruption does not affect the sequence editor, OI or TestStand engine, so the error does not occur.
If the error usually occurs after calling a specific step it is good to review how TestStand is configured to call the code module. If you have access to the source code of this step's code module, it is recommended to do a code review of the code itself. If this does not find anything, try to simplify the scenario by slowly removing TestStand steps and pair down the source code to try to isolate what might be causing the problem.
This type of intermittent error is always difficult to isolate.

TestStand 4: 17502 System Level Exception

I attempted to run an TestStand 3.1 Sequence file on my new computer in TestStand 4. And I had a 17502; system level expection run time error for a particular function call. The sequence access the function or module from a .dll that was developed in LabWindows/CVI 7. However, this code module works on my other station that runs TestStand 3.1. I also attached the example of the code that's causing this run-time error in TestStand 4.

I did step through the code to see which function call was causing error. However, when I save the sequence file at a TestStand 4.0 sequence file and executed the sequence this system level exception error did not occur again.

Gets error "-17502; System Level Exception" while running the custom Step in NI TestStnad 2010

I have a custom teststand step which works like For loop in TestStand. Previously I was using LV 2009 and NI TestStand 4.2.1 and this step was working fine. Recently I upgraded my system to LV 2010 and TestStand 2010, since that it is not working.
When I run the step it gives error "-17502; System Level Exception". I have attached error screenshot.
I am using NIFlowControl.dll in this step.
Please do the needful.

The source code for NIFlowControl.dll ships with TestStand. Did you perhaps
1) modify the code and rebuild this dll in teststand 4.2.1, but did not move your changes into the 2010 version and recompile the 2010 version?
Or
2) Move your 4.2.1 version of this dll to 2010 in which case it might be missing important code that exists only in the 2010 version. It's best to redo your code changes to the 2010 version and recompile that if needed.
Also ideally your modified version of NIFlowControl.dll should be located in the teststand public directory rather than the program files directory.

17502 System Level Exception

Hi Everyone,
I've done the searches and read all the posts related to the"-17502; System Level Exception" error message.
I've quadruple checked the CVI function and the function call in TestStand to make sure the data types matched and that pointers were indeed pointers and not passed by value.
Since the error stayed, I decided to do a mock code where I removed the parameters in the CVI function to the point where the only parameter is now the CAObjHandle thisContext, as shown in the image below.
Even with a single parameter, I continue to get that error. And yes, the error is related to the function 'MemTest'.
Since I narrowed the list of parameters to this single one, is there something I'm over-seeing with the CVI function and the way it is called by TestStand? (I am rusty at TestStand.. I didn't think I was that rusty )
It does not make it inside the function since the first step is a message saying that it got in (kinda like Hello World).
- sigh -

Hi RayF,
I knew I could count on you...
I get the error when I run the sequence. I had a fully working sequence and added this one additional step, which is a new test.
The Adaptor should be okay as it has not changed from the original code. I can check, but ut should be fine. As a matter of fact, if I choose continue instead of terminate, the program continues happily afterwards. So I think I did something stupid which is small and should be easy to fix.. It just evades me at the moment.
I'm "old school". I created the function prototype from within LW-CVI from scratch. I didn't think of using the Create Code button. I will try that.
I will also try removing everything else from within the function and simply have an "Hello World" message popup.
Thanks RayF,
RayR

System Level Exception. Error code -17502

Hi,
I have an initialize test step which is written in LabWindows/CVI and I call
that step from TestStand.
In that test step I initialize one dll, first I load DLL (the handle goes to
the global variable) and finally I get the function pointers. When this step
ends, I go back to the TestStand and I got this error. Do you know what is
wrong and how should I do this dll loading because I need this handle later?
TIA,
-Harri

I think something must be happening in either the DLL_PROCESS_ATTACH: of DLL main in the loaded dll. It might be trying to do something which can be causing the system level exception.
System level exception can also be caused because you are calling a dll function incorrectly ie passing a I16 instead of a I32 in the parameters.
I might also be trying to call/release a function reference which is not valid.
I would suggest you to step into your code and make sure that all your reference are valid if and when you call/release them.
You might want to try to trap the 17502 error by following the Knowledge Base link given below

Intermittent -17502; System Level Exception

Running Test Stand 4.2.1, Labview 2009
In my test stand sequence I launch a Labview VI. Usually it works just fine, but occasionally I get a -17502; System Level Exception error. Once it happens it keeps occuring until I open the Labview Vi, re-save it, and then reload it in Test Stand. I don't change anything about the VI or the Test Stand step, I just open the VI, save and close it.
Any ideas what is happening?

What drivers are you calling in your VI? What is your VI doing? Can it potentially take different paths through the VI different times that it is called? Can you consistently reproduce the issue?
Here is a link that might be useful: http://forums.ni.com/t5/NI-TestStand/17502-System-Level-Exception-in-Run-Time/td-p/1892207
Can you reproduce it with other VIs? Or is it just this one VI?
Regards,
The VI is using OPC via serial to talk to another device. It just reads a variable for its current status and compares it to an expected value. There are a couple different paths it can take depending on if an error is present, the value read is the same as the expected value, etc. but all the paths do very similar things. The error only occurs with this VI and cannot be reproduced consistantly.

I had a labview VI that had a diagram disable structure on it. TestStand loaded it all right, but threw a -17502; System Level Exception at runtime.

System level exception -17502

Hello,
I get the following error, when I want to execute a labwindows dll step in testsystand 3.1:
"system level exception -17502"
The strange thing is that on 2 other PCs this step is working with same version of teststand and LabWindows
what could be the problem?
regards samuel

That is strange.. The other PC's do not have this error although they have the same dll's...
My experience with that error code has been "array or buffer out of bound". The buffer size was not sufficient to hold the data that was passed to it. Interesting, indeed... hummm....

RUN TIME error - Error code: system level exception -17502

1. During running of my sequence in a TestStand Operator Interface   i got following run-time error:
    Details: Error executing substep 'Post'.Parameter 'Input cluster 6 [OUT]': System Level Exception.
    Location: Step 'sequence 'SequenceFilePostStep' in 'Sequence X.seq'
    In my SequenceFilePostStep i transfer some information between the LabVIEW 8.0 and TestStand 3.5.
    In my xxx.vi I have 6 clusters and every cluster from 14 to 20 variables.
   The cluster #6 has 70 variables.
   Perhaps, the error that i got is from cluster #6 due to 70 variables? is it to much for cluster?
2. What can i check? How i can fix it?
Please ask questions if you do not understand something, i am want to resolve it!
   Thank you to all!

Thank you Sam R,
I think that error caused due the overflowing of some string that i have in my cluster.
Because i also get I/O open file error and the name of that file i hold at my cluster.
Do you think that the incorrect string can caused to that system level exception error?
p.s. screenshot is attached

Premiere Pro CS6 - A low level exception has occurred in ImporterMPEG

Hi Adobe Community,
I'm having a bit of an issue with the ImporterMPEG.prm plugin for Premiere Pro CS6 that's causing playback and exporting issues.
Computer Specs: Win7 PC, NVIDIA GeForce 6150SE nForce 430 graphics card
Description: After playing back video for a while, Premiere will eventually start repeatedly reporting "A low level exception has occurred in ImporterMPEG". The preview player will be completely frozen, and I'll be unable to export. The exporting will fail with a generic "Unexpected error" message.
This issue has only started a week ago. Until now, I've been able to use Premiere Pro CS6 with no issues. If possible, I'd like to avoid upgrading to CC 2014, because the CS6 version was working fine before.
So far, I've tried a few things:
• Deactivating and reactivating (which, by the way, apparently doesn't help subscription users like me, per my recent chat with Adobe support on this issue)
• Uninstall and reinstall (I didn't know about the CC Cleaner tool at the time, so I haven't tried a clean uninstall yet)
• Change the Preview File Format in Sequence Settings (from I-Frame Only MPEG which had worked since I installed the software over a year ago to Microsoft AVI)
• Crying silently to myself (this did not help, the computer is cold and cruel)
• Clearing out the media cache (which I'd never done before and let it get up to ~75GB without me noticing)
• Moving the plugin from its location in Program Files, hoping that maybe Premiere Pro would notice it was missing and to try to find a new fresh one (it didn't work)
So far, only the Preview File Format change seemed to bring relief, but the bad behavior came back after about a week.
I'm thinking maybe the ImporterMPEG.prm plugin got corrupted somehow? The one notable thing I can remember with the computer in the last few weeks was a power event that shut down my computer unexpectedly. I think I had Premiere Pro open at the time.
If it's relevant, I mostly work with .AVI, .MP4, and .TS files in my projects, all varying resolutions and FPS. I'm usually working with about 1GB of files in a project, very rarely more than 2GB.
Has anyone else had this issue? Or, even better, has anyone else resolved this issue?
Thanks!

But really, the real solution for me was to not update Premiere Pro CS6 after a reinstall. The most recent updates just do not like my computer, I guess.
Figured I should post this solution here in case anyone in the future has this problem. (relevant: xkcd: Wisdom of the Ancients)

Export Error, Error compiling movie. "A low-level exception occurred in: H.264"

Hi
I'm still learning AE. I'd appreciate any help. I can export to Windows. Can't export to Vimeo SD 25 fps in H.264 either. When I try to compile via media encoder the following I get this message.
- Encoding Time: 00:00:00
07/30/2013 03:01:03 PM : Encoding Failed
A low-level exception occurred in: H.264 (Exporter)
Export Error
Error compiling movie.
Unknown error.
Movie Spec screen grabs:

Update: no error on the following, media encoder didn't throw any errors... must be the project. Disk cache is 120GB BTW. I was able was unable to run through YouTube HD 1080P 23.96 FPS.

Error Msg -A Low-level exception occurred in: Adobe Player

I have CS6 installed, all the latest patches, etc. It's been working fine for months.In the last week Pr is unable to playback all of my footage (Native 5D mark III h.246 and Canon xf305 footage). Whether it is on the timeline or in the source panel.
The Error message i get it this: A Low-level exception occurred in: Adobe Player (player).
Using Adobe CS 6.0.3
Windows 64 Bit 8 GBs RAM
Happens in new projects and old.
New timelines also affected, it appears.
Was not happening as recently as two days ago.
No changes made to the computer.
Only changes is that I have combined timeines (Imported) from one project to another.
Video shows yellow or Green.
I have rerendered the footage to show all green on timeline.
Only way around it is to reboot the computer, it comes back after a while. The problematic timelines work fine for a while, then this starts happening.
I deleted the media cache database folder after exiting Pr.
Didn't seem to change anything. I just got the error again. Things seem to be curiously messed up. I tried to render a sequence out to MXF. The headless crashed each time, (not totally unusual, but it couldn't complete even once). I also got an error message when I bypassed the Media Encoder and just went strait to rendering it out within Pro. It managed to continue to render it to MXF but when I got done and imported it into Pro, it didn't play the clip when I clicked on it.
The interesting thing to me is that to totally clear Adobe from RAM, I have to go into Task Manager and kill the process after exiting the program (in lieu of rebooting). So it's not closing properly, it appears. Once I kill the process and reopen the app, I can then play the sequence, for a while. It's very curious. Task manager also shows lots of RAM open, no memory leaks at work, nothing unusual. It appears, to be just choking on footage, sort of like it can't quite process the audio (like when you bring in new footage and it has to process that audio). What's happening is like it sees the audio at first when I bring it in at startup of the app, then loses it. If I exit without killing the Premiere process (or shutting down the machine), then it still exhibets the behavior on startup again.
So this project is large, for me. It is showing as 34 MBs. I have a wide variety of clips at play here, but only MXF Canon from the xf305 and MOV from the Canon 5D. The MXF are the default sequence(s) unless I shot nothing but MOV.
I have tried rendering the visualization, all green lines on top but that doesn't seem to fully help. It does play the footage for a while.
There are no special effects added, yet.
Is it worth re-installing Premiere? This has cost me the better part of a day screwing around with this.
Let me detail this again:
Premiere is installed on C There hundreds of GBs of storage avaialble there.
All project files are on F which is a RAID 1 array. It appears to be functioning normally. 800 GBs free space on 2TBs.
All Renders are taking out to an external drive like I always do. Lot s of space available there too.
Anyone have an idea how to fix this?

Is this any better? Cut and pasted plain text.
