Intermitant time outs between 6720 switches on ISL

I have a single fabric with a 10G ISL connection between switches and I keep getting time outs between them. Not sure what to do now.

 

Any help? What am I missing?

 

Switch one port config:

sw6720-D# sh run int te 202/0/1
interface TenGigabitEthernet 202/0/1
 mtu 1522
 fabric isl enable
 fabric trunk enable
 no shutdown
!

 

Switch one show interface:

sw6720-D# sh int te 202/0/1
TenGigabitEthernet 202/0/1 is up, line protocol is up (connected)
