This is on RELENG_8 dated 2011/09/28.
If you want me to test it on my em0 interface (which is what actually has
an IP configured, etc.) and do a full reboot, I can do that. Let me
know.
So there may have been some rc.d framework changes that address your

root cause. The solution was to have mpath probe against a dedicated

Item #2 above seems to be the kicker. Is there anything in the works

I see 100baseTX there, not 1000baseTX. This speed is being selected via
autoneg (auto speed/duplex negotiation).
Whatever switch you're connected to is not properly negotiating the
speed.
What brand and model of switch is

This is probably because checksum offloading was being done on the NIC.

within about 15 minutes, state-mismatch was up to 22. We use tcp.closed
of 5 (which means 15 seconds).
Workarounds such as "no state" suffice, but if you use rdr rules, you
MUST track state, which means there's no way of winning in that case.

Try adjusting some of these sysctl values:
hw.acpi.disable_on_reboot
hw.acpi.handle_reboot
You're using VMware, which may or may not behave properly anyways.

s the two NICs
together to give you the equivalent of 2000mbit of traffic? I don't
know.
Does the corruption you see go away if you install a separate NIC (e.g.
an Intel NIC) in a PCI or PCI-e slot, and disable the onboard NICs
(should be "MAC LAN: Disable" on both the primary
separate driver (presumably igb(4)) than a "hacked up" em(4) driver
trying to handle tons of IC revisions. A good example of the insanity
the latter causes is nve(4) vs. nfe(4). :-)
