Frame Position and Frame time TDMS files are empty - Priority 9

[floesche]

Every once in a while, the log files related to the frame are empty. On one of the setups with G4 Host v235 this happens as often as once every other day (sample from early to mid April 2022).

One example of the out generated is attached. The error became visible during the alignFly_LPTC script, which generated the following output (but this is not the cause, rather the moment when the problem was detected).

Hard to replicate. Is there a quick fix? If not, it's not worth the time trying to fix this issue…

I think we should table this for now because this will be very hard to fix without it being easily replicated.
