Dovelet, is this just happening on off3 and off4?, what are the other
stats for the interface when you show them. How a bout a "show
frame-rlay pvc", any issues there ? There must me a reason. Do a "shut"
and then "no shut" on each interface and then watch for a while. What
IOS are you running on that 7200 ?, are there any bugs that could be
fixed by updating the IOS ?, dig around at Cisco's site as well.
