That was my experience as well. 2514 suddenly became non-responsive when we copied some large files (totalling about 9GB) from one box (4.1.1R) to another (4.3R) . (Boxes were in two different nets) From the source box I could not even ping the router. It said "No route to host" all of a sudden. Manually adding routes didn't work either. Basically it did not respond to machines from 1 class C net. Other net was working OK. Pretty wierd! > Pretty much.
