PAUP Help...

I have been running phylogenies and have been having this problem with PAUP running maximum parsimony where it is supposed to find the 1000 most parsimonious trees.

The number of trees left to swap went up and rapidly went from 691 to 975 at last check. Has anyone had that happen? I haven't seen it before and trying to make sense of it. Any help would be greatly appreciated.

Thanks!
