Excessive tcp resends from my ASA
Posted on 2016-10-08
I'm seeing an inordinate amount of tcp denies in my ASA that are not attributable to my access lists. The logging is over 90% tcp deny with mostly PSH ACK and some ACK and very seldomly FIN.
There doesn't appear to be a network performance degradation, but I am concerned that there is an issue, plus it is filling up my syslog server more rapidly.
I will send a sample log output soon, but I am looking for ASA experts and tcp transaction experts to help me find out what is going on.
