One possible reason is that the session was closed according to the "tcp-halfclose-timer" before all data had been sent for that session. For that I'll need to know the firmware you have running so I can tailor one for your situation. By default in FortiOS 5.0,5.2 tcp-halfclose-timer is 120 seconds. Super odd because even with the bad brick in everything at the end of the ptp link was showing up and talking, web traffic just wouldn't work. Although more and more it is showing the no session matched. Blaming the firewall is a time-honored technique practiced by users, IT managers, and sysadmins alike. We get a " no session matched" (log_id=0038000007) message several thousand times a day for various different connections on our Fortigate 310B (4.0 MR3 patch 9) If you have an active session with a specific src/dst ip and src/dst port, all traffic matching those ips and ports will be matched to that session and no new session will be created even if the client attempts to create one, while the old one is active.
