I've removed a number of workunits and the feeder is now blazing along extra fast. Work should be flowing significantly better.
Now that work is flowing, I'll be working on updating the work generator for SubsetSum@Home to make sure it keeps a minimal (<10k) number of workunits available, but auto generates them as needed to prevent this from happening again. Hoping to have the updates in tonight.
Thanks for your patience in dealing with all this, especially during the midst of a pentathalon!
