So, in other words, you upgraded from pf 4.4 to pf 4.5 and problems 
arised immidiately. Looks familiar. I switched to th 10.x in the same 
case. And I wait for the situation to resolve, and I'm not upgrading my 
others productions running 8.x and pf. But I didn't see complains about 
packet losses or connection drops (I saw once, but it was related only 
to the max states limit). All that I saw were panics (after applying 
some particular sets of rules), LORs and freezes (still not sure whether 
the freezes were about zfs or pf). So, in my case, there were some 
definitely diagnoseable problems with pf. I've also seen a horrible 
performance degradation when using route-to/reply-to rules, but this was 
fixed somewhere between 9.0-RELEASE and 9.1-STABLE.
