random reboots: in_cksum causing this?

For the past month or so.  I've been seeing random reboots from my firewall
box.  I am presently running: 4.11-RELEASE-p13.  I am observing the
following entries in /var/log/messages that occur right before or lead to
the reboot eventually:

Jan  1 14:42:30 myhost /kernel: in_cksum_skip: out of data by 10103

I'd provide more..but its not exactly reproducible at will.

The box uses pppoe to connect to the web and provide internet to a private
LAN via an adsl connection.  The reboots are very sporadic and don't appear
to be deterministic...in terms of time.  This can happen as often as 3x a
day or I wouldn't see it for 1-2 weeks.  There could be a number of
transfers going on or nothing much in terms of traffic.  The box is not a
compute server.  It does nothing else.

I have found some references to this in_cksum problem on the web.  But they
were posted 4-5 months before I upgraded /usr/src to p13.  So I don't think
its related.  I don't have much to go on.  Anyone have any ideas or has at
least seen this?
