I'm using supermicro boxes (dmesg below) as vpn routers. IPsec+gre+bgp.
After a few days uptime the boxes start reporting 8% system cpu, and at the
same time
they become unresponsive on the network approx every 10 seconds.
Any idea on how to find the reason for this is appreciated.
I have around 20 of these boxes running open and freebsd, so far all of the
openbsd boxes
display this behaviour using amd64, i386, sp and mp, 4.6 and various 4.7
snapshots.
I only see this on these specific supermicros. This happens on the devices
that don't
move any traffic as well.
Regards Tony
