As a test try putting some fair-queuing on your multilink interface and see if the problem lessens/goes away, play with the values until you find your sweet spot.

The underlying T1 serial ints don't have many drops (maybe 0.1% of those found on the multilink int worst case). Any idea what would cause drops on the interface? There is no QOS or anything like that on the mu2 int, just an inbound ACL. Google search didn't really turn up anything too useful. CPU and memory on the routers look pretty good. T1s seem pretty clean, the couple routers I watched closely didn't have any T1 errors during the time frames when drops where occuring. All are running recent 12.3 or 12.4 mainline releases. Utilization on the multilink interface was low (under 25%), at least according to the 30 second load interval.
