Greetings all.
I have been playing around with GRE tunnel over IPSec. A couple of times
I have seen either of the endpoints panic about 5GB into a large
transfer using ssh between 2 nodes which live within the networks
connected by this tunnel. These transfers aside, there isn't much going
on in this tunnel but with a lot of activity this event is recurring.
Both endpoints are running OpenBSD 6.3 with all current patches applied
by syspatch and the hardware used is PCEngines APU2
(http://pcengines.ch/apu2c4.htm). I also tried with plain 6.3 (ie. no
patches) which was the original state of these endpoints.
Here is the info which I have been able to gather. I can't show you
'ipsecctl -sa' at the moment since the node which just panic'ed needs
somebody on the other end to power cycle it.
I can pursue getting more info if needed.
Any thoughts?
Thanks a lot!
Joao
