It seems I have problem with the STP. It is not a trunked link. I have two catalysts connected via cross calble (fastethernet 0/24) and both of them are connected to a 7206 (fastethernet 0/1) via BVI interface. If a set the fastethernet 0/24 in bloking (as per James.Kilby suggestion, thanks) I resolve the problem, but it's just a workaround and not a solution. By the way I don't understand why I have this loop: I have the same HW/SW configuration is 5 sites and only in this one I'm experiencing this problem.

Also, I have seen some servers with teamed nic's try to etherchannel and it will flap like that unless the switch is also configured for it. Hope this helps.
