Hi,
I have noticed that recently recon-all is taking a lot longer than usual to finish. It used to take around 30 to 48 hours, but the last couple that I have done are taking a whole week. It seems to get stuck in a repetitive step and it numbers each iteration like this:

It continues to do that for days. I have run it in 2 different computers and it makes no difference. Any ideas why this is now taking so long and how to make a bit faster?
Thanks!
