WUs regularly hang at or near 100% without ever finishing

You're doing CPU tasks.  This thread has been more about the behaviour of GPU tasks.  Yes, the data comes from the same Large Area Telescope on the Fermi satellite but the searches are quite different.  If you think the 'hang up' just happened for the first time then you haven't been paying proper attention :-).

Both CPU tasks and GPU tasks do have two stages to the processing.  The main processing is completed at 89.997% for GPU tasks and 89.979% (not 98.979%) for CPU tasks.  After that comes a 'followup stage' where the 10 most important potential candidates are re-evaluated in double precision.  During the followup stage the progress counter appears stalled.  If you leave it alone, it will complete, just as yours did.  The followup stage can be quite short for GPU tasks where there is a capable GPU, but can easily take 10-30 minutes (or longer) for CPU tasks.  It also varies with the particular data file 'in play' at the time.

Good news. Each WU uploaded, after approx. 20 minutes. Results were "completed and validated".

For future reference, that's exactly what you should expect for all FGRP5 CPU tasks.  Just don't stress when they appear to pause at 89.979%.  They will finish when they're good and ready, all on their own :-).

 

Cheers,
