Some suggestions would be to check that all network interfaces are negotiating gigabit back to the switch, and that if you are using jumbo frames then all interfaces are indeed using jumbo frames. A useful check to verify 2 way jumbo frames connectivity is by using the ping command, doing: ping -c 1 -M do -s 8900 $hostname should tell you whether or not it is working. Best of luck!
