That > seems buggy to me. Does it still do so if you set either "arp_ignore" or "arp_filter" (I can never keep those two straight)? Could be the "weak-end-system" design of the stack at work here. That allows any interface in the system to respond to an ARP request for any of the IP's assigned to any of the interfaces. > worse, it continues to do it after unconfiguring > eth0:1 and eth0.
