I have a 3COM 3900 with gig modules for which I create a back bone with and connect servers to. Over time the gig modules become congested to the point that they become unusable the access LED stays solid. Moving to a different module solves the problem. Going back to the same module after some lag time seems to work again. Does anyone have any suggestions. It seems to be more of a problem with the server connections. Does anyone have any suggestions.
