EXCESSIVE PACKET LOSS WITH MASTER IAP

I have a wireless network with IAPs.
There are two cluster with 30 APs each one. the masters for each clusters are IAP 215.
Both AP masters and virtual controllers of each cluster have excesive packet loss, only them, because the others APs response without packet loss.
if i change the place of the masters APs to other switch happen the same.
I need your support because the network administrators (wired) sayes that there not problem in the switches.
I need to know why do i have to many packet loss with the master APs and by Consequence with the VCs too, and the others APs in the same switch doesn´t have it.
Other problem is that i have to many of the next log in the masters:

Re: EXCESSIVE PACKET LOSS WITH MASTER IAP

What firmware version are you on? Might be worth upgrading but I would contact TAC first.
Cheers
