hey
we have some problem with old system that are beeign stuck after some tome it is working and on the logs we see the session end reason is "tcp-reuse" my questions are:
1) what should be happaning on the network flow for this end-reason log to apear
2) will the FW generate some traffic to the client and server to "close" their existing connection?
thanks

#1 tcp-reuse means when the session finished the 3 or 4 ways FIN, and closing down the session (TCP Time Wait), during the TCP time wait, the same client and server is starting up a new session but using the same source and destination port as the session that just closed and couting down. That is when you will get the tcp-reuse.
A session is reused and the firewall closes the previous session.
See the sesssion about TCP Half Closed nad TCP Time Wait Timers.
#2 FW usually does not generate traffics to either side, unless you instructed it to.
