Hi,

1. Error Message %PIX-4-405001: Received ARP {request | response} collision from IP_address/mac_address on interface interface_name

Explanation

The firewall received an ARP packet, and the MAC address in the packet differs from the ARP cache entry.

Recommended Action

This traffic might be legitimate, or it might indicate that an ARP poisoning attack is in progress. Check the source MAC address to determine where the packets are coming from and check to see if it belongs to a valid host.

2. Please verify the interface error counters, maybee one Interface is exhausted an not able to receive the failover hello messages.

Please verify this with show blocks ------------------

If you see the zero than you have following problems.

1. too much traffic

2. faulty hardware
