Thank you for the replies - we've got to a point where we _think_ we're "just" tickling a known issue: 987243

In certain instances, the Ethernet interface on the UTA2 X1143-R6 adapter
 and onboard ports might stop sending packets due to lack of transmission
 resources. 

So now we're just lining up for a reboot at a suitable outage window, and a code update later if that's done the trick. 

In the interim though - does anyone know of a good workaround for rerouting my intercluster (replication) traffic? 
I can't failover that interface to another node - and as the interface is "up", but not "working" my replication jobs have failed.

Ok...gotta say it....

Have you tried physically unlinking and relinking the network connection?

Occasionally, I have see this fix weird problems.

Also, have you checked the port settings on the switch to make sure they line up as expected?

Do you have portfast enabled for the LACP ports (spanning-tree portfast trunk?)
