[atlas] tracemon false join

looking at TraceMON (for 128292864), it appears as if the traces for a bunch of sources converge at a common node before failing. but they do not. they fail at different points as one can see if one looks at the result details or at khipu. what am i misunderstanding here? this is very misleading to a novice. i see one madly clicking at the apparent point of failure desperately wanting its ip address. of course, i would never make that mistake :) randy
