LabVIEW hangs on IMAQ call

[BruceMoyer]

LabVIEW hangs periodically and when I look at where it hangs, lately it's been in an IMAQ call.  It is occurring quite frequently and I've tried repairing LabVIEW and IMAQ, and also uninstalling/reinstalling IMAQ (VAS).  I'm using LabVIEW 2017 (17.0.1f4 64-bit) and VAS 2017.1 (IMAQ 17.0). 

What could be causing this?

Thanks,

Bruce

Is the problem camera specific?

Could it be that you are trying to dispose an image that is currently in use in parallel by some processing Vi for instance ?

Thanks for your reply.  Unfortunately, that time that it got stuck was at the beginning of the program.  It's gotten stuck on other IMAQ calls as well.  Yesterday it was the IMAQ ImageToArray.vi.

So far I haven't seen the issue in an exe (which is good), but it's been annoying having my program crash so often.  When it crashes, the LabVIEW environment is still functioning (so I'm able to determine where it is), I just can't stop my program cause it never comes out of the IMAQ dll.

Thanks,

Bruce

It just hung on the IMAQ Image Bit Depth.vi.

Now it froze either in the ImageName property node (or possibly the IMAQ Dispose)!  This is really slowing me down!  Don't know what to do!

Here's the screenshot.

Now it hung on a .NET call.  So I guess it isn't limited to IMAQ.

I haven't seen the hang in a long time since re-compiling all the VIs in my project.  I also reinstalled IMAQ but I think the key was to re-compile all of the VIs.

Lately, I have the same Problem with hanging IMAQ Copy.vi. Sometimes when starting the program, sometimes when stopping it. As you, I can get into the block diagram and see, that it hangs in the IMAQ VI.

I tried to repair Labview (2020x64) and NI Vision.

I tried to recompile the code.

This behaviour is new and I never had troubles before with this project.

Any help from NI? Any suggestions?
