There's another possible reason for those logs.
In our case, we have 2 SPARC Solaris that have the same public IP
address ( different internal IP address of course ), and the Cisco load
balancer would do a check by sending TCP_SYN to each of them internal IP
addresses that are mapped to that public IP.... but once it receives a
TCP_ACK, the router would send a TCP_RST or TCP_FIN. This will tell the
router that the service on that IP & port is alive. It seem to do this
every minute.
