Timed Loop Question

I have observed on 3 machines in 3 months a timed loop getting stuck.  These have been running LV2015,16,17 on Windows.  Nothing complicated is going on in the timed loop.  The counter shows that the timed loop has been entered but the timer never fires so it gets stuck.  I have waited for about 2 hrs and the timed loop never exits.

 

The issue once it occurs seems to be static.  You can exit LabVIEW and/or restart the machine and the timed loop will not function correctly.  If you force recompile or change something in the VI to force a recompilation the timed loop functionality returns to normal.

 

Just curious if anyone happen to seen this before or know how windows timer resource gets stale?
