EIGRP on Cat 3550/3560 problems...

Does anyone know if there's a common problem with running EIGRP between Cat
3550/3560 switches??
It seems like every time I set up EIGRP between my switches I have this
issue where the adjacency goes
up and down.... as if he hold-timer expires. But, right after it goes down
it comes back up. I've tried
increasing the hello & hold timers but that hasn't worked. I'll paste the
message below:

148.48.114.101 (Vlan114) is down: retry limit exceeded
