Eigrp flaping - retry limit exceeded

Hello everyone, I have this topology

Sw2{vlan 11} --- {f0/1.11}R1

I am getting this messages on SW2

*Mar 2 03:31:29.036: %DUAL-5-NBRCHANGE: EIGRP-IPv4:(10) 10: Neighbor
112.10.3.1 (Vlan11) is down: retry limit exceeded
*Mar 2 03:31:33.809: %DUAL-5-NBRCHANGE: EIGRP-IPv4:(10) 10: Neighbor
112.10.3.1 (Vlan11) is up: new adjacency

Any advise?
Thank you!

Here is a debug eigrp packet on SW2
