Hi Emil:
I am running 12.1(6), I am not sure what's
default queue method it uses but I think
it uses fifo accoding to sh int resutlts.
I will make sure fair-queue is turned off
on all routers and see if it makes diffrence.

Hello
Once I have similar problem
Try to turn off weighted fair queuing
no ip fair-queue - in the interface configuration
And please tell me what software are you using and if my solution helped you
Regards
