[Cerowrt-devel] odhcp6c went crazy flooding Comcast with DHCPv6 SOLICITs

It sounds like a 32 bit overflow of some kind (23.x days *s)
In looking through the relevant commits for odhcpd, I don't see any
fixes targetted at it.
We had another similar bug with the ra flooding thing comcast was
doing but I think this is different.
an strace would be good to have.
opkg update
opkg install strace
strace -p t`pidof odhcp6c` 2> /tmp/strace.log
wait a bit, do a control-c, send the log.
I realize this is a very severe bug, but at one level, I'm happy -
we're making 52 days of uptime without a problem! Next stop, YEARS.
