Is there a limit to the number of threads I can allocate in LabVIEW?


Yes. Threads use system resources, so the system configuration limits the ultimate number of threads that can be created. Users may set the number of threads LabVIEW uses in a particular execution system by running This VI can be found in C:\Program Files (x86)\National Instruments\<LabVIEW Version>\vi.lib\Utility\sysinfo.llb\ . In general, the upper limit is in the hundreds of threads, but the overall performance of the computer is likely to suffer as the number of threads increases due to thread swapping overhead.
