I have Internet connections in two different sites from the same ISP.  This
ISP uses Frame Relay for their Internet connections.  I have two T1s in one
site and three T1s in another connected to the ISP.  The three T1s are
bundled in a Multilink Frame Relay connection.  The two T1s are load
balanced via BGP.

In both sites I am seeing a lot of input and output queue drops on the
router interfaces connected to the ISP.  In the site with the two T1s I see
the drops on each of the serial interfaces and in the site with the three
Internet T1s I see drops on the Multilink Frame Relay bundled interface and
not on the serial interfaces.

I am running a Cisco 2811 in the site with the three Internet T1 and a Cisco
3825 in the site with the two Internet T1s.  These routers are running the
12.3T IOS train (required for hardware support).

In one of the sites I have Internet T1s to a different ISP that uses PPP
encapsulation on the links and I do not have any problems with queue drops.

Any help on this would be appreciated.

Thanks.

If you are using WFQ do fair-queue 256 256 256 if that doesn't help you might want to switch to FIFO and do: hold-queue 375 in, hold-queue 375 out. Let me know if that does not help.
