I am having input drops all the time, no matter how high or low I set
the incoming hold-queue.

The OSPF and IBGP interfaces approx. 30 minutes after I cleared the counters:

TenGigabitEthernet8/1 is up, line protocol is up (connected)
  Input queue: 0/2000/622/622 (size/max/drops/flushes); Total output drops: 0

TenGigabitEthernet9/1 is up, line protocol is up (connected)
  Input queue: 0/4096/1664/1664 (size/max/drops/flushes); Total output drops: 0

TenGigabitEthernet9/2 is up, line protocol is up (connected)
  Input queue: 0/4096/1916/1916 (size/max/drops/flushes); Total output drops: 0


These links are not congested! Te9/1 is the busiest with maybe 6.5 out
of 10 Gig. The other two are below 5 Gig.
