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. Eugene.
