Labview hangs while loading a project

I have a large project that suddenly will cause LabView to slow to crawl, and eventually hang, while loading.  It will load normally when Windows is booted into safe-mode, which leads me to think a service, virus-protection, etc. is getting in the way.  But I think I've eliminated all of those possibilities.  

 

More details:

  • Labview 2015, 32-bit
  • Windows 7
  • The project has ~500 VIs, with a few hundred additional non-VI files.  I believe the total number of files loaded is ~3000 (when VI.lib and User.lib are included).
  • There are 3 RT targets (sbRIO-9606,  sbRIO-9607, Desktop)
  • I can open the top-level VIs outside of the project
  • The longest I've waited is ~1 hour
  • Things I've tried:
    • Mass compile of project directory
      • Failed in normal boot
      • Succeeded in safe-mode
    • Forced binary compile
      • Succeeded in safe-mode
    • Clear compiled object cache
    • Applying Labview updates
    • Applying Windows updates

Any ideas would be greatly appreciated.  Thanks.

I have a similar-sized LabVIEW RT Project (my target is a PXI system, no FPGA code).  When I load the Project, the Target is off.  There are 600+ VIs and about 140 TypeDefs or custom controls.  It takes at most 20" to load the Project.

 

I don't have much experience with cRIO Projects.  I assumed that during Development, all of the code lived on the PC until it was Deployed to the RIO.  Is there any compiled FPGA code involved?

Yes, both of the RIO targets have FPGA VIs and compiled bitfiles.

 

The day before this started, the project would load in 3 or 4 minutes, and has been that way for 2 years.

 

I also tried reverting to a previous revision, but that didn't help.

Hi Joe,

I encourage you to contact NI support. This looks like an issue that could take time to resolve and it would be better I think if you have a dedicated NI engineer that can can reproduce the issue and verify what is going on
