SXH2, Netflow bug that crippled rtr-2 and shortly thereafter rtr-1 in
a redundant pair. Control-plane was half dead, but did not reboot.
Needed maual intervention for recovery.

We have disabled Netflow on all chassis running SXH2, and are testing
SXI (we need SXI for IPv6 VRF stuff anyway, so I'm hoping this will
work for us.)

When it comes to IOS, hardware failures are the least of our worries...
