Error -2519 at TDMS file I/O on Windwos Server 2012

[DSachse]

Hello everybody,

I have a weird problem with an application and hope you can help me:

I have a  LabVIEW program as service running on a Windows Server 2012 R2 machine that should create pdf reports on user request. It takes entries from a database, puts the content into a tdms file and sends the result to DIAdem. All in all it works fine for a small amount of requested datasets.

The other day, I requested a large amount of reports (something like 5000+) and after round about 4800 reports I got the error -2519. After this, I couldn't send any new request without getting this error immediatly. After shutting down and restarting the service, I could request reports again up to nearly the same number of reports (even with different datasets ... always up to the same amount of requested reports).

So I decided to make some tests with the tdms VIs and wrote the VI attatched. It creates a tdms file and afterwards it just opens and closes the file in a loop only writing the loop counter as an attribute. Now here comes the weird thing: I've built the application using LabVIEW 2014. I tried the application using different Systems:

Windows 7: work fine

Windows 10: works fine

Windows Server 2008: works fine

Windows Server 2012: works fine as Long as I run the program as a local user. When I run it with Administrator priviledges, it opens and closes the file round about 4800 times. Afterwards, it fires the Error -2519. I'm even not able to restart the program using the run button. But when I Close the application again, it works again up to the same Point.

Does that Sound familiar to anyone? My next test step is trying to build the application with a different LabVIEW Version. I'll let you guys know if the Problem still appears.

Kind regards

Daniel

Hi Daniel,

I found following post to your error.

http://forums.ni.com/t5/Real-Time-Measurement-and/tdms-2519-error/m-p/2570325#M13927

at the very last point it is saying:

... looks like dll mismatch 64/32bit.

Error occurs by using 32-bit LV15.

64-bit-tdms.dll  (1047kB) resides at ../Program Files/National Instruments/Shared/TDMS and

32-bit tdms.dll (769kB) at ../Program Files (x86)/ni\Shared\TDMS.

Rename 64-bit-version to tdms_64.dll and copy 32-bit-dll to that (64-bit) folder is my solution.

Hope it's useful.

May be this explains the different bebavior in th different machines.

Best

Hi,

I've tried this solution and unfortunately it doesn't work for me. The effect is that the program doesn't run anymore when I try to runs it with local priviledges. Running it as adminstrator leads to the same error as before.

Kind regards

Daniel
