ICMP type 3 -- "Destination unreachable". Sound like the one (or both) of the two servers thinks the other is a next hop for a given destination. If you can capture the ICMP packet, and look at the latter 40 bytes or so, you should see the IP & TCP headers of the packet that triggered the "unreachable" message. From that, you should be able to figure out which server's routing table needs to be fixed.
========================= Hi i have a strange communication between two of my Linux server, it's ICMP packet on port 3. Do you know what it could be ?
