Please don't misinterpret this post: ZFS's ability to recover from fairly
catastrophic failures is pretty stellar, but I'm wondering if there can be
a little room for improvement.

So... I've been diagnosing this problem with IPSEC on FreeBSD

clients. The configuration is that dozens of FreeS/WAN clients
connect to the FreeBSD IPSEC gateway --- FreeBSD uses Racoon to
authenticate and exchange keys with them. Thi

I'm sending traffic to (ie: it expects a different tunnel per firewall

Did we change something in the routing socket's datagram between 7.0 and
