I have recently been having problems with the de_nbody files never finishing. They will start, elapsed time continues to increment but the time remaining also increments instead of declining. These tasks will also use every cpu available (ryzen 1600 6 cores 12 threads) which means no other projects I am connected to get any processor time. I finally abort these files and things proceed normally until another one is scheduled. Some of them do run and finish normally but it is getting annoying.

Anyone know why this is happening and what to do about it?

The n-body workunits don't work for everyone, they work for alot of them but not everyone and it's a work in progress to keep up with all the new features and cpu's that come out all the time. I suggest just running the standard units, you can run 11 of them at a time if you also use your gpu for crunching.

I started this thread a few days ago and it looks like we're having the same problem. In my case, it is only occasional and restarting BOINC gets the tasks working again. Also, I first noticed the problem after updating BOINC to v7.10.2. (So, you might want to try v7.8.3.)

If there are any moderators out there, it's OK with me if you would like to combine our 2 threads. And, retitling would probably be a good idea, as well - maybe something like "3-CPU Nbody Task hang-ups"

It happens to me on nbody and on single CPU tasks. Started killing the long running stalled tasks (what a waste) before realising rebooting fixed the problem for a while.
