We have tried pulling the ACTIVE Sup720. Still gets the error. So I think it not a Hardware problem.
Upgrading the Code to :
6509:
#show module
HW FW SW
Module 5 4.6 8.4(2) 12.2(33)SXI4
Module 6 5.2 8.4(2) 12.2(33)SXI4
We are having intermittant connection issue.
Can difference in HW version cause this?
