I am also seeing this, especially when a website/browser/tab is closed 
but the remote site is still sending data I think.

I am using the same basic pf.conf I have used for client machines for a 
while, but there is not much other than pf options and allowing traffic 
out (modulate state for tcp, keep state for everything else). I do have 
scrub, and antispoof rules for the interfaces, as well as a block log 
all at the top.

For now, like i said, I've only seen the state key mismatches with web 
traffic. Also, synproxy state seems to hang all traffic.
